How much whipping cream and 2% milk should be mixed to obtain 35 gallons of milk with 4% butterfat?
2% milk has 2% butterfat
Whipping cream has 9% butterfat
-----
Equation::
fat + fat = fat
0.09x + 0.02(35-x) = 0.04*35
-----
9x + 2*35 - 2x = 4*35
7x = 2*35
x = 10 gallons (amt. of whipping cream needed)
35-x = 25 gallons (amt. of 2% mild needed)
