Quizplus · Accepted Answer

Andy has 15 quarters. To solve this, let's use a system of equations where x is the number of quarters and y is the number of half dollars. We have two equations: x + y = 23 (since there are 23 coins in total) and 0.25x + 0.5y = 7.75 (since the total value of the coins is $7.75). Solving these equations simultaneously, we find that x = 15, meaning Andy has 15 quarters.
