Answer:
- 3 pennies
- 2 nickels
- 3 dimes
- 1 quarter
Explanation:
You know that 3 pennies are involved, because $0.68 cannot be made without them.
Then 6 coins must make up 65¢. If 1 is a quarter, then the remaining 40¢ must be made using 5 coins. 4 dimes is too few, and 8 nickels is too many. However 3 dimes and 2 nickels is just right.
Bobby gave the cashier 1 quarter, 3 dimes, 2 nickels, 3 pennies.
