Question

Under her cell phone plan, Shaniece pays a flat cost of $48 per month and $3 per gigabyte. She wants to keep her bill at $61.20 per month. Which equation could be used to determine x

�
x, the number of gigabytes of data Shaniece can use while staying within her budget?

Answer 1

Explanation:

flat cost = $48/mo

rate = $3/Gb

x = number of Gb

budget = $61.20/mo

61.2 = 48 + 3x rearrange to solve for x

3x = 61.2 - 48 = 13.20

x = 13.20/3 = 4.40 gigabytes

She can use 4.40 gigabytes and stay within her budget

Answer 2

61.20= 48 + 3x
3x= 61.20 - 48.00 = 13.20
x= 13.2/3 = 4.4
