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.
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 copiers, and c, the number of color copies that the customer paid for at the print shop?
A. b + c = 16 0.29b + 0.15c = 74
B. b + c = 74 0.29b + 0.15c = 16
C. b + c = 16 0.15b + 0.29c = 74
D. b + c = 74 0.15b + -.29c = 16
