A customer paid a total of $16 for 74 copies at a print shop. Some of the copies were black-and-white copies, and the rest were color copies.

Question

Each black-and-white copy cost $0.15.

Each color copy cost $0.29.

Which system of equations can be used to find `b`, the number of black-and-white copies, and `c`, the number of color copies that the customer paid for at the print shop?

Answer 1

0.15b + 0.29c = 16
b + c = 74
