Have you ever bought concert tickets online? Do you have a cellphone? These prices can be found using multi-step equations!
Let's say that tickets to see your favorite band cost $50 each and the website you are using charges a $25 fee per order. How many tickets t can you buy using your $225 gift card? This situation can be represented with an equation!
225=50t+25
Let's say your phone company charges you 10 cents per text message t, 5 cents per minute on the phone m, and a $45 monthly flat fee. You total bill b is then represented by the following equation.
b=0.10t+0.05m+45
Multi-step equations can help us find a missing value (or values) when there is more than one thing that needs to be considered.
