16 servings
because there are 4 cups in a quart, and two quarts is 8 cups.. if 5 cups of milk makes 10 servings there is half a cup in each serving.. so 8/.5 is 16
The constant term in the equation is -20 because you will always be subtracting 20 no matter how big x is
The answer is 8/9 i believe.
you shouldnt answer if you really dont know you noodle head , the answer is 2.54
