Question

Alan received a 25.00 gift card for a photo center. He used it to buy prints that cost 7 cents each. The remaining balance B (in dollars), on the card after buying x prints is given by the following function. B(x)=25.00-0.07x What is the remaining balance on the card if Alan bought 20 prints? dollars

Answer 1

To find the remaining balance on the card after Alan bought 20 prints, we need to substitute x = 20 into the function B(x) = 25.00 - 0.07x.Substituting x = 20 into the function, we get:B(20) = 25.00 - 0.07(20)Simplifying the expression, we have:B(20) = 25.00 - 1.40B(20) = 23.60Therefore, the remaining balance on the card after Alan bought 20 prints is $23.60.
