A "Collector's Coin Set" contains a one dollar coin, a fifty-cent coin, a quarter (= 25 cents), a dime (= 10 cents), a nickel (= 5 cents), and a penny (= 1 cent). The Coin Sets are sold for the combined face price of the currency. If Colin buys as many Coin Sets as he can with the $25 he has, how much change will Colin have left over?

Combined value = 1 + 0.5 + 0.25 + 0.1 + 0.05 + 0.01 = 1.91.

He can buy 13 sets for 24.83 and the change will be 17 cents.
