Question

Quizplus · Accepted Answer

Let the number of quarters be $q$ and the number of half dollars be $h$. We have two equations: $q + h = 15$ (since there are 15 coins in total) and $0.25q + 0.5h = 5.50$ (since the total value of the coins is $5.50). Solving these equations simultaneously, we find that $q = 8$ and $h = 7$. Therefore, Andy has 8 quarters.
