In the American money system, there are five coins in regular use. The penny is worth 1 cent, the nickel is worth 5 cents, the dime is worth 10 cents, the quarter is worth 25 cents, and the half-dollar is worth 50 cents.
If you use no more than 4 of any type of coin, how many different ways can you make change for 1 dollar (100 cents)?
