A total of six family members will appear in a portrait and two of the family members may sit in the front row, there will be fifteen combinations of family members that may sit in the front row.
if you are multiplying by 5, then the blue needs to be 25 quarts and the yellow needs to be 15 quarts not 9. If you are multiplying by 3 then it would be 9 quarts yellow and 15 quarts blue. hope this helps :)
