99 cents
Posted: Posted April 9th by Xhin
 There are various ways of making 99 cents from change, all of which require at least 4 pennies:
9 dimes, 1 nickel, 4 pennies
1 quarter, 3 dimes, 5 nickels, 44 pennies
3 quarters, 2 dimes, 4 pennies
That last one is how you make it in the least amount of coins possible. This is because of the following four rules:
1. A quarter counts as one coin
2. A dime counts as one coin
3. A nickel counts as one coin
4. A penny counts as one coin
However, if a quarter counted as three coins, then suddenly 9 dimes, 1 nickel, 4 pennies is going to be a better option.
Can you find a set of these four rules where most or all of the ways of making 99 cents are equal?
