Math Question

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?
A \( b+c=6.00 \)
\( 0.08 b+0.15 c=68 \)
B \( b+c=68 \)
\( 0.15 b+0.08 c=6.00 \)
c \( b+c=6.00 \)
\( 0.15 b+0.08 c=68 \)
D \( b+c=68 \)
\( 0.08 b+0.15 c=6.00 \)
