Needs vs Wants
Simple Arithmetic with Money:
Decision-Making Basics:
If I buy X, I might not afford Y)
Maya has a part-time babysitting job that pays $100 per week.
She has some regularly occurring expenses:
Maya also has savings goals:
When it comes to money and making choices about how to spend it, it is helpful to understand the difference between wants and needs.
Wants are things that we would like to have, but we can live without. Needs, on the other hand, are essential things that we require to live and be healthy. These are things that we cannot do without. We need them to survive and to participate in daily activities. Here are some examples.
| Wants | Needs |
|---|---|
| Toys and games | Food and water |
| Entertainment, such as movies or concerts | A place to live |
| Treats, such as candy or snacks | Clothing and shoes |
| Luxuries, such as a new phone or a vacation | Basic school supplies |
Sort the items into wants or needs. Remember: needs are essential, wants are nice to have!
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.
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.
&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.
$20 - $10 = $10 Emma has $10 left after paying for her needs.
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 wants a new backpack that costs $40. She plans to save $5 each week.
40/5 = 8weeks It will take Emma 8 weeks to save enough money for the backpack.
$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.
$60/4=$15 Emma needs to save $15 each week in order to buy the backpack and shoes before school starts.
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 + $5 + $10 = $20 Emma can save $20 each week now.
Substitute values
Calculate quotient
It will take Emma 3 weeks to save the $60 she needs.
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!
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.

The laptop I like costs $780 and I would really like to say that I bought it within a year of starting to save. |
$780 ÷ 52 = $15 She needs to save $15 each week to reach her goal of $780 in 52 weeks.
Lunch+Fun+Miscellaneous=Total $25+$20+$10=$55 We can subtract this from her income to find the amount of money she saves. $100 - $55 = $45 per week Remember that for the first 52 weeks, $15 per week will go towards her new laptop. This means that $30 per week can be put into her college fund. $45 - $15 = $30 Let's calculate how much money she will save for college during the first year.
During the second and third years, the entire $45 will go into her college fund each week. Let's see how much she will save during those two years!
Next, let's add these numbers together to see how much money she will have saved after three years. $1 560 + $4 680 = $6 240 Maya will have saved $6 240 for college.
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.
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.
Sort these from best to worst for saving money.
Let's analyze the options one at a time.
When you buy things on impulse, you are not thinking carefully about your purchases. You might regret them later. This can lead to wasting money on things you do not really need.
Buy things on impulse * *
If you do not keep track of your spending, you might not know where your money is going. This can make it hard to save money and achieve your financial goals.
Don't track your spending *
This is a smart way to shop. By comparing prices, you can find the best deals and save money.

Let's calculate the total cost of the movie and the book. The movie costs $15 and the book costs $10. $15 + $10 = $25 Since Kayla only has $20, she cannot afford both.
Let's look at the given options for how she can adjust her wants and stay within her budget.
| Option | Reasoning | Conclusion |
|---|---|---|
| A. Only buy the book | The book costs $10, which is less than $20. | This plan works! ✓ |
| 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. * |
