Answer 1

9514 1404 393

Answer:

• 20 dimes
• 68 nickels

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
