Problema Solution
A dairy has 400 quarts of whole milk containing 5% butterfat. How many quarts of low-fat milk containing 1.5% butterfat should be added tp produce 2% butterfat.
Answer provided by our tutors
Let 'x' represent the number of 1.5% milk which must be added to 400 quarts of 5% butterfat in order to produce 2% butterfat milk.
0.02(400+x)=0.05*400+0.015x
x=2400
So 2400 quarts of 1.5% butterfat milk must be added.
