Problema Solution
Cream is approximately 22% butterfat. How many gallons of cream must be mixed with milk testing at 2% butterfat to get 70 gallons of milk containing 4% butterfat?
Answer provided by our tutors
let
x = gal of cream that has approximately 22% butterfat
y = gal of milk that has 2% butterfat
x + y = 70
0.22x + 0.02y = 0.04*70
by solving the above system of equations we find:
x = 7 gal
y = 63 gal
