If you mean how many one ounce servings would be equal to 1 gallon plus 1 quart, it would be 160 one ounce servings. There are 128 oz in a gallon, and 32 oz in a quart, so when you add them together, it is a total of 160 ounces. If you meant more than just 1 ounce per serving, just divide the number of servings into 160, and that will be your answer. For example, if you meant how many 6 ounce servings, you would divide 6 into 160, which would be 10 servings.
