What is the system of equations for the problem: Ray has 59 quarters and dimes. He has a total of $13.25?

Let q = quarters, d = dimes. 50q + 20d = 2650, q + d = 59

Let q = quarters, d = dimes. 25q + 10d = 1325, q - d = 59

Let q = quarters, d = dimes. 25q + 10d = 1325, q + d = 59 (correct)

Let q = quarters, d = dimes. 25q + 10d = 1300, q + d = 59
