Alex has 84 quarters and nickels worth a total of $17.80.

Which equation can be used to find q, the number of quarters Alex has?

0.25q + 0.05(q – 84) = 17.80
0.05q + 0.25(84 – q) = 17.80
0.25(q – 84) + 0.05q = 17.80
0.05(84 – q) + 0.25q = 17.80

Let q = number of quarters. Then nickels = 84 − q. Value: 0.25q + 0.05(84 − q) = 17.80.

So the correct choice is:
0.05(84 – q) + 0.25q = 17.80.
