Under her cell phone plan, Melanie pays a flat cost of $48 per month and $3 per gigabyte. She wants to keep her bill at $72 per month. Which equation could be used to determine x, the number of gigabytes of data Melanie can use while staying within her budget?

• 48x + 3 = 72

• 72 + 3x = 48

• 48 + 3x = 72

• 48x + 3x = 72

Answer explanation

Let x = the gigabytes of data used per month

$48 is the flat cost

$3 per gigabyte

Total Budget for the month $72

48 + 3x = 72
