Question

Under her cell phone plan, ximena pays a flat cost of $40 per month and $4 per gigabyte. She wants to keep her bill under $80 per month. Which inequality can be used to determine gg, the maximum number of gigabytes ximena can use while staying within her budget?.

Answer 1

4g + 40 < 80

Explanation:

Let g = number of gigabytes.

Since 1 gigabyte costs $4, the cost of the gigabytes is 4g.

The flat cost is $40.

total cost = cost for gigabytes + flat cost

total cost = 4g + 40

She wants the bill to be under $80, so the total cost must be less than 80.

4g + 40 < 80
