How do you make 19 coins equal a dollar?

Answer 1

There are 9 different solutions to this puzzle. It is tied for the most number of solutions for a specified number of coins (the other is making 15 coins equal a dollar). The first solution uses 0 pennies, just nickels and dimes, and should be pretty easy to find if you remember that 20 nickels equals a dollar. Two solutions use 5 pennies, either with just nickels and dimes, or with 1 quarter. There are four solutions that use 10 pennies (if you allow half dollars). And two solutions that use 15 pennies (one that uses half dollars). This kind of puzzle is always more fun if you try to systematically find ALL the answers instead of just the first one you come across. Have fun!
