Problem
Using only pennies, nickels, dimes, and quarters, what is the smallest number of coins Freddie would need so he could pay any amount of money less than a dollar?
Solution
To have less then a dollar, the most it could be is 99 cents. You could use 3 of the quarters, then 2 dimes, and 4 pennies to make 99 cents with least coins. So the total of coins is 6 coins.
