Felipe received a $40.00 gift card for a photo center. He used it to buy prints that cost 8 cents each. The remaining balance, B (in dollars), on the card after buying

x prints is given by the following function. =Bx−40.000.08x

What is the remaining balance on the card if Felipe bought
40
prints?

For better representation, I think the function is written as:

B(x) = 40.00 - 0.08x

This is much more comprehensive. The variable x represents the number of prints. So, if x=40 prints, we replace this to the x in the equation to find the balance B.

B = 40 - 0.08(40)
B = $36.8
