Understanding Wants and Needs
When it comes to money and making choices about how to spend it, it is helpful to understand the difference between wants and needs.
Needs are essential things that we require to live and be healthy. They include:
- Food and water
- A place to live
- Clothing and shoes
- Basic school supplies
These are things that we cannot do without. We need them to survive and to participate in daily activities. Wants, on the other hand, are things that we would like to have, but we can live without them. They include:
- Toys and games
- Entertainment, such as movies or concerts
- Treats, such as candy or snacks
- Luxuries, such as a new phone or a vacation

Income vs. Expense
The money you earn or receive regularly, like from a part-time job, chores, or a weekly allowance, is your income. On the other hand, the money you spend on things like food, rent, gas, or phone bills goes towards your expenses.

Understanding Savings and Spending
Savings is money that is put aside instead of being spent right away so that you can use it later for emergencies or big goals. On the other hand, spending refers to using your money to buy things you need or want. In particular, planned spending is when you decide to spend money on wants, like a new game or concert tickets, and make sure to include it in your budget.

What is a Budget?
A budget is a plan for how to use your money wisely. It shows how much money you will get, how much you expect to spend on things you need and want, and how much you plan to save over a set time.

Budgeting a Weekly Allowance
Emma gets $20 a week for her allowance. She needs to use $10 to pay for her school lunches. She also wants to spend $5 renting movies and $4 on snacks when she hangs out with her friends.
{"type":"multichoice","form":{"alts":["School lunch","Movie rentals","Snacks"],"noSort":false},"formTextBefore":"","formTextAfter":"","answer":[1,2]}
b How much money does Emma have left after paying for her needs?
{"type":"text","form":{"type":"math","options":{"comparison":"1","nofractofloat":false,"keypad":{"simple":true,"useShortLog":false,"variables":["x"],"constants":["PI"]},"rendered":false},"text":" "},"formTextBefore":"$","formTextAfter":null,"answer":{"text":["10"]}}
c If Emma wants to save at least $5 each week, what can she cut from her spending?
{"type":"multichoice","form":{"alts":["School lunch","Movie rentals","Snacks"],"noSort":false},"formTextBefore":"","formTextAfter":"","answer":[1,2]}
Hint
a A need is something necessary. A want is extra or fun.
b Subtract her needs from her total allowance.
c Focus on things she could live without.
Solution
a To determine which expenses are wants, we need to recall that a want is something that is extra or fun and is not necessary. Emma's expenses are:
&School Lunches:&$10 &Movie Rentals:&$5 &Snacks:&$4 School lunches are necessary, but movie rentals and snacks are not. The expenses that are wants are movie rentals and snacks.
b To find out how much money Emma has left after paying for her needs, we need to subtract her necessary expenses from her total allowance. We know that her necessary expense is $10 for school lunches. Emma's total allowance is $20. We will subtract her needs from this amount.
$20 - $10 = $10 Emma has $10 left after paying for her needs.
c To find out what Emma can cut from her spending, we need to focus on things she could live without, which are her wants. We know that she wants to save at least $5 and she has $10 left after paying for her needs. Emma's wants are movie rentals and snacks.
Total Cost of Wants $5 + $4 = $9 She can cut either snacks or movie rentals — or both — to free up at least $5 for savings.

Emma's New Backpack
Emma wants a new backpack that costs $40. She plans to save $5 each week.
a How many weeks will it take for Emma to save enough money?
{"type":"text","form":{"type":"math","options":{"comparison":"1","nofractofloat":false,"keypad":{"simple":true,"useShortLog":false,"variables":["x"],"constants":["PI"]},"rendered":false},"text":" "},"formTextBefore":null,"formTextAfter":"weeks","answer":{"text":["8"]}}
b Emma decides that she would also like to buy a new pair of shoes that cost $20. How many total weeks does she need to save now?
{"type":"text","form":{"type":"math","options":{"comparison":"1","nofractofloat":false,"keypad":{"simple":true,"useShortLog":false,"variables":["x"],"constants":["PI"]},"rendered":false},"text":" "},"formTextBefore":null,"formTextAfter":"weeks","answer":{"text":["12"]}}
c Suppose the new semester starts in one month. How much money would she need to save each week in order to have her new backpack and shoes in time for classes to start?
{"type":"text","form":{"type":"math","options":{"comparison":"1","nofractofloat":false,"keypad":{"simple":true,"useShortLog":false,"variables":["x"],"constants":["PI"]},"rendered":false},"text":" "},"formTextBefore":"$","formTextAfter":null,"answer":{"text":["15"]}}
Hint
a How many times does she need to save $5 before it adds up to $40?
b Add the prices together before dividing.
c Divide the total amount of money needed by the number of weeks in a month.
Solution
a The backpack costs $40, and Emma saves $5 per week. To find out how many weeks it will take Emma to save enough money for the backpack, we need to divide the cost of the backpack by her weekly savings.
40/5 = 8weeks It will take Emma 8 weeks to save enough money for the backpack.
b The backpack costs $40, the shoes cost $20, and Emma saves $5 per week. First, we add the prices together to find the total cost.
$40 + $20 = $60 To find the total number of weeks Emma needs to save money to buy these things, we divide the total cost by her weekly savings. $60/5 = 12weeks Emma needs to save for 12 weeks to buy both the backpack and the shoes.
c The backpack and shoes together cost $60 and there are about 4 weeks until the semester starts. To determine how much Emma needs to save each week, we divide the total cost by the number of weeks.
$60/4=$15 Emma needs to save $15 each week in order to buy the backpack and shoes before school starts.

Earning Extra to Save Faster
Emma wasn't going to be able to save enough money each week to buy all of the things she wanted for the new semester so she decided to help out her next door neighbor to earn the extra money. Now her weekly income includes:
- $5 savings from her allowance
- $5 for walking their dog
- $10 for mowing their lawn
a With her new income, how much can Emma save each week now?

Hint
a Add her savings from her allowance to her income.
b Divide the cost of her items by the amount saved each week.
c How many weeks are left until the new semester after she's met her savings goal?
Solution
a Emma's weekly income now includes $5 from her allowance, $5 for walking the dog, and $10 for mowing the lawn. To find out how much Emma can save each week now, we need to add her savings from her allowance to her new income.
$5 + $5 + $10 = $20 Emma can save $20 each week now.
b Emma needs is $60 in total to buy her backpack and shoes and she can now save $20 each week. To find out how many weeks it will take her to save enough money, we divide the total cost by her new weekly savings.
Time = Total cost/Weekly savings
SubstituteValues

Making Maya's Budget
Now that we've learned so much about what it means to make a budget, let's look back at Maya's situation. Remember that she has a part-time job that pays her $100 per week. She wants to make sure she uses her money wisely so that she can afford her regular expenses and meet her savings goals.
We need to know how much each of her expenses cost her on a weekly basis to help her make her budget. This is what she tells us.
| Expense | Weekly Cost |
|---|---|
| School lunch | $25 |
| Fun activities | $20 |
| Miscellaneous things | $10 |
Now let's remember her savings goals!
- Buy a new laptop within the next year
- Start growing her college fund
If we want to decide how much money can be set aside for each of her goals, we need some more information about each one. Her goals need to be more specific. Let's see what she says when we ask her for some more details.
a How much money should Maya save each week for her new laptop in order to meet her goal?
{"type":"text","form":{"type":"math","options":{"comparison":"1","nofractofloat":false,"keypad":{"simple":true,"useShortLog":false,"variables":["x"],"constants":["PI"]},"rendered":false},"text":" "},"formTextBefore":"$","formTextAfter":null,"answer":{"text":["15"]}}
b How much money will Maya have saved for college by the time she starts classes in 3 years?
{"type":"text","form":{"type":"math","options":{"comparison":"1","nofractofloat":false,"keypad":{"simple":true,"useShortLog":false,"variables":["x"],"constants":["PI"]},"rendered":false},"text":" "},"formTextBefore":"$","formTextAfter":null,"answer":{"text":["6240"]}}
Hint
a There are 52 weeks in a year.
b How much does she save each week before she purchases the laptop? And how much does she save each week after she purchases the laptop?
Solution
a Since we are setting a weekly savings goal for Maya, we need to remember that there are 52 weeks in a year. Now we will divide the total cost of the laptop by the number of weeks.
$780 ÷ 52 = $15 She needs to save $15 each week to reach her goal of $780 in 52 weeks.
b First, let's determine Maya's total weekly savings. She earns $100 and has three expenses that total $55 per week.

Let's start by calculating Tiana's weekly savings. She earns $10 for babysitting, $5 from chores, and $3 from her allowance. $10 + $5 + $3 = $18 Tiana saves $18 per week.
We want to know how many full weeks it will take Tiana to afford the concert ticket. The ticket costs $72 and she saves $18 per week. Let's divide the cost of the ticket by her weekly savings.
$72/$18=4
It will take Tiana 4 full weeks to afford the ticket.
Now let's see how much Tiana will have left over if she saves for 6 weeks. We already know that she saves $18 per week. Let's multiply to find her total savings.
$18 * 6 = $108
Next, we will subtract the cost of the ticket from her total savings.
$108 - $72 = $36
Tiana will have $36 left over.

Luca wants to buy a $60 backpack in 3 weeks. To find out how much he needs to save per week, let's divide the cost of the backpack by the number of weeks. $60/3 = $20 Luca needs to save $20 per week.
Let's consider the situation where Luca only saves $15 per week for 3 weeks.
$15 * 3 = $45
He will have only saved $45. Let's compare this to the price of the backpack.
$60 - $45 = $15
Luca will be $15 short.
All of the given options would help Luca meet his goal.
- Earning extra money would help him make up for the missing $15.
- If the backpack that he wants cost at least $15 less, buying the cheaper backpack would be an achievable goal.
- Waiting longer to buy it gives Luca more opportunities to save enough money.

Ava wants new shoes that cost $40 and a new hoodie that costs $30. To find out how much she needs to save in total, let's add the cost of the shoes and the hoodie. $40 + $30 = $70 Ava needs to save a total of $70.
Ava earns $14 each week. To find out how many weeks it will take her to save enough money, let's divide the total amount she needs to save by the amount she earns each week.
$70/$14 = 5weeks
It will take Ava 5 weeks to save enough money.
If Ava gets a one-time bonus of $10, she will already have that money and will not need to save as much. Let's subtract the bonus from the total amount she needs to save.
$70 - $10 = $60
She still earns $14 each week. Let's divide the new amount she needs to save by the amount she earns each week.
$60/$14≈ 4.29
Since we cannot save a fraction of a week, Ava will still need 5 weeks to save enough money.

| B. Go to the movies and skip the book | The movie costs $15, which is less than $20. | This plan works! ✓ |
| C. Find a free movie screening and buy the book | If she finds a free movie screening, she only needs to pay for the book. The book costs $10, which is less than $20. | This plan works! ✓ |
| D. Borrow money to do both | Borrowing money is not the same as not spending it — debt is its own expense. | This plan is not within her budget. * |
| E. She is already within her budget | We already calculated that Kayla does not have enough money to buy both, so this option is incorrect. | She is not within her budget. * |
