Exercise 3 Page 11

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! 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. Multi-step equations can help us find a missing value (or values) when there is more than one thing that needs to be considered.
