Question

Under his cell phone plan, Justin pays a flat cost of $56 per month and $5 per gigabyte. He wants to keep his bill under $65 per month. Write and solve an inequality which can be used to determine xx, the number of gigabytes Justin can use while staying within his budget

Answer 1

Answer:

56 + 5xx < 65

xx < 1.8

Step-by-step explanation:

56 + 5xx < 65

subtract 56 on both sides

56 + 5xx < 65

-56 -56

5xx < 9

divide by 5 on both sides

5xx/5 < 9/5

xx < 1.8 gigabytes
