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?

q + d = 6
25q + 10d = 33
q + d = 6
0.25q + 0.1d = 33
q + d = 33
25q + 10d = 6
q + d = 33
0.25q + 0.1d = 6

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?

q + d = 6
25q + 10d = 33
q + d = 6
0.25q + 0.1d = 33
q + d = 33
25q + 10d = 6
q + d = 33
0.25q + 0.1d = 6

You answer would be the last two equations
q + d = 33
0.25q + 0.1d = 6
