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?

• b + c = 6.00

  0.08b + 0.15c = 68

• b + c = 68

  0.15b + 0.08c = 6.00

• b + c = 6.00

  0.15b + 0.08c = 68

• b + c = 68

  0.08b + 0.15c = 6.00
