Question

your cellphone plan costs 29.99 per month plus 0.18 for each text message you send or receive. you have at most $34 to spend on your cell phone bill. what is the maximum number of text messages you can send or receive next month.

Answer 1

22.28

Explanation:

the inequality would be 29.99+0.18x≤34 because 29.99 is the constant. and the 0.18 is the 'slope' if this were being graphed. and it and it can be equal to but no more than $34.

you subtract 29.99 from both sides

0.18x=4.01

divide by 0.18

x≤22.28

but you cant send a partial text so it rounds down to 22
