Problema Solution

A pint of cream has 8.4% butterfat.

How many pints (pt) of skim milk containing 2% butterfat should be added to 1 pint of cream to obtain a mixture containing 6% butterfat?

Answer provided by our tutors

Let P be the pints of skim milk to be added.

0.02P + 0.084(1.0) = 0.06(1 + P)

0.04P = 0.024

P = 0.6

0.6 pints of skim milk must be added.
