Question

Under her cell phone plan, Violet pays a flat cost of $38 per month and $3 per gigabyte. She wants to keep her bill under $80 per month. Which inequality can be used to determine xx, the maximum number of gigabytes Violet can use while staying within her budget?

GPT-5 mini · Answer

Let x = gigabytes. The bill is 38 + 3x, and she wants it under 80, so
38 + 3x < 80.

Solve: 3x < 42 ⇒ x < 14.

Thus x must be less than 14 (so at most 13 whole gigabytes).
