Sumo · Answer 1

3 dimes, 9 pennies, and 5 nickels

Step-by-step explanation:

Call the number of dimes d. Then, we will have 3d pennies and d + 2 nickels. The value for each group is 10d, 3d, and 5d + 10. Add these to get 18d + 10. This is equal to 64 cents, as stated in the question. So, setting these equal, we get that d = 3, and there are 3 dimes, 9 pennies, and 5 nickels.
