Answer:

  • 20 dimes
  • 68 nickels

Step-by-step explanation:

Let d represent the number of dimes. Then the number of nickels is 8+3d. The total value of the coins, in cents, is ...

  5(8+3d) +10d = 540

  40 +25d = 540

  25d = 500

  d = 20 . . . . number of dimes

  8+3d = 8+3·20 = 68 . . . . number of nickels
