Answer 1

To find the remaining balance on the card after buying 30 prints, we substitute x = 30 into the function B(x) = 50.25 - 0.09x:

B(30) = 50.25 - 0.09(30)
B(30) = 50.25 - 2.7
B(30) = 47.55

Therefore, the remaining balance on the card if Lucy bought 30 prints is $47.55. Answer: \boxed{47.55}.
