Since the number of nickels (5 cents) is the same number as pennies (1 cent), their sum goes in multiples of 6 cents.

Assume there are N of each of pennies and nickels

N amount left

1 32

2 26

**3 20**

4 14

5 8

6 2

Since 20 cents equals two dimes (10 cents), we conclude that there are

2 dimes

3 nickels

3 pennies.
