Find how many quarts of 6% butterfat milk and 3% butterfat milk should be mixed to yield 60 quarts of 4% butterfat milk.
FAT in ingredients = fat in final solution
x = 6% amount
then 60 - x = 3% amount
6% (x) + 3% (60-x) = 4% ( 60)
.06 x + .03 (60-x) = .04 (60) solve for 'x' the amount of 6% then 3% amount = 60-x
