Solving Coin

Problems

Suppose you have some coins in your wallet. In order to determine the

amount of money you have, you would multiply the value of each type of

coin by the number of coins of that denomination and then add the answers.

For example, if you have 6 nickels, 4 dimes, and 2 quarters, the total amount

of money you have in change is

6  5 cþ 4  10 cþ 2  25 c

¼ 30 cþ 40 cþ 50 c¼ 120 cor$ 1 : 20 :

In general, then, to find the amount of money for

Pennies – multiply the number of pennies by 1c

Nickels – multiply the number of nickels by 5c

Dimes – multiply the number of dimes by 10c

Quarters – multiply the number of quarters by 25c

Half dollars – multiply the number of half dollars by 50c
