Stuart has some 2-ounce, 3 -ounce, and 4-ounce weights. how many different ways can stuart combine the weights to make a total of 12 ounces?

2 + 2 + 2 + 2 + 2 + 2 = 12

2 + 2 + 2 + 2 + 4 = 12

2 + 2 + 4 + 4 = 12

4 + 4 + 4 = 12

3 + 3 + 3 + 3 = 12

3 + 3 + 2 + 2 + 2 = 12

3 + 3 + 4 + 2 = 12

I get 7 ways.
