Make a List #5

Hints and answers

Lonnie has a large supply of quarters, dimes, nickels, and pennies. In how many ways could she make change for 50 cents?


You can make a systematic list for this one (four columns, with how many quarters, dimes, nickels and pennies for all the ways to make change for 50 cents), but it's going to be a long list! Can you think of ways to count all the ways without making the complete list?

As always, be sure to explain the work you did to arrive at your answers!
