Question

Your cell phone plan costs $34.99 per month plus $0.12 for each text message you send or receive. You have at most $40 to spend on your cell phone bill. What is the maximum

number of text messages that you can send or receive next month?

Answer 1

41

Explanation:

Let the number of text messages be x.

`34.99+0.12x \leq 40 \\ \\ 0.12x \leq 5.01 \\ \\ x \leq 41.75 \\ \\ \lfloor x \rfloor=41`
