Question

Karen received a $50.75 gift card for a photo center. She used it to buy prints that cost 10 cents each. The remaining balance, B (In dollars), on the card after
buying x prints is given by the following function
B(x) = 50.75 -0.10x
What is the remaining balance on the card if Karen bought 30 prints?

Answer 1

Answer: 47.75

Step-by-step explanation: It explains at the end that she bought 30 prints. You would take 30 and just plug it in for X. So the formula would look like this, B(x)=50.75-0.10(30).
