A customer paid a total of $6.00 for 68 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 $0.08. Each color copy cost $0.15. 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?

Choose TWO correct answers.

• b + c = 6.00

• 0.15b + 0.08c = 6.00

• b + c = 68

• 0.08b + 0.15c = 6.00

• 0.08b + 0.15c = 68
