Question

David received a $35.75 gift card for a photo sensor he use it to buy prints that cost $0.25 each the remaining balance b (in dollars) on the card after buying x prints is given by the following function b(x)= 35.75 - 0.25x what is the remaining balance on the card if David bought 30 prints

Answer 1

To find the remaining balance on the card, we plug in x = 30 into the given function b(x):

b(x) = 35.75 - 0.25x

b(30) = 35.75 - 0.25(30)
= 35.75 - 7.5
= 28.25

Therefore, the remaining balance on the card if David bought 30 prints is $28.25.
