Question

Quizplus · Accepted Answer

The total value of the coins is $4.75. Let's denote the number of quarters as Q and the number of half dollars as H. We have two equations: Q + H = 17 (since there are 17 coins in total) and 0.25Q + 0.5H = 4.75 (since the total value of the coins is $4.75). Solving these equations simultaneously, we find that Q = 15, meaning Andy has 15 quarters.
