Martha and George have 2 gallons of milk left in their fridge. They have several different desserts to make for a bake sale, but they are not sure if they will have enough milk. They need 8 cups of milk for the ice cream, 2 pints of milk for the dump cake, 5 cups for the bread pudding, and 3 quarts for the cream pies. Will they have enough milk to make everything on their list? If so, how many extra cups will they have? If not, how many cups will they be short?
