Question

A phone service offers a data plan with a $25 monthly fee and charges $10 per gigabyte download.

How many gigabytes can a customer download and spend at most $75?

What linear inequality with variable x represents this situation?

What is the solution to that inequality? Enter the solution as an inequality using x.

Answer 1

The answer is for the.... 2nd question is 245$

Answer 2

your expression: 25+10x
#2: 25 + 10x = 75
10x = 75-25
10x = 50
10x/10 = 50/10
x = 5
The customer can download 5 gigabytes at the most

Linear equality:
25+10x (plug in the 5 into the x, for x = 5)
25 + 10(5) = 75
then plug in 1 - 5 (since you can only download 5 at the most)

that is your linear

hope this helps
