Quizplus · Accepted Answer

Let the number of nickels be $n$ and the number of quarters be $q$. We have two equations based on the given information: $n + q = 13$ (total coins) and $0.05n + 0.25q = 2.25$ (total value in dollars). Solving these equations simultaneously, we find that $n = 5$ and $q = 8$, meaning there are 5 nickels.
