Quizplus · Accepted Answer

Let the number of dimes be x and the number of nickels be 5x. The value of the dimes is 0.10x and the value of the nickels is 0.05(5x) = 0.25x. The total value is 0.10x + 0.25x = 0.35x = $37.45. Solving for x gives x = 107, so there are 107 dimes and 5*107 = 535 nickels.
