B=35.50-0.15x
What is the remaining balance on the card is Salma bought 50 prints?

Answer 1

To find the remaining balance on the card after buying 50 prints, we substitute x = 50 into the equation B = 35.50 - 0.15x:

B = 35.50 - 0.15(50)
B = 35.50 - 7.50
B = 28

Therefore, the remaining balance on the card is $28.
