Cream is about 22% butterfat and low-fat milk is about 2% butterfat.
How many gallons of cream must be mixed with 18 gallons of low fat milk to make whole milk that contains 4% butterfat?
-------------
Equation:
fat + fat = fat
0.22x + 0.02*18 = 0.04(x+18)
---------
Multiply thru by 100.
22x + 2*18 = 4x + 4*18
18x = 2*18
x = 2 gallons (amt. of cream needed in the mixture)
