Bobby bought a bag of candy at the candy shop. His total came up to $0.68. He gave the cashier 9 coins. How many of each coin did Bobby give the cashier

3 pennies 2 nickels 3 dimes 1 quarter

Step-by-step 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.
