Martin has a combination of 33 quarters and dimes worth a total
of $6. Which system of linear equations can be used to find the
number of quarters, q, and the number of dimes, d, Martin has?
A.-q + d = 625q + 10d = 33
B.-q + d = 6 0.25q + 0.1d = 33
C.-q + d = 33 25q + 10d = 6
D.-q + d = 33 0.25q + 0.1d = 6 - Answer q + d = 33
0.25q + 0.1d = 6
