Question

Diane received a 35.75 gift card for a photo center. She used it to buy prints that cost 5 cents each. The remaining balance, B (in dollars), on the card after buying X prints is given by the following function.

What is the remaining balance on the card if Diane bought 30 prints?

Answer 1

The remaining balance, B, on the card after buying X prints is given by the function B = 35.75 - 0.05X.

Substituting X = 30 into the function, we get B = 35.75 - 0.05 * 30 = 35.75 - 1.5 = 34.25.

Therefore, the remaining balance on the card if Diane bought 30 prints is $34.25.
