Answer provided by our tutors
let 'x' represent the amount of 4% butterfat milk added into '30-x' 1% butterfat milk
we solve for this equation:
0.02(30) = 0.04x + 0.01(30-x)
--------------------
solve for the amount of 4% butterfat milk
--------------------
x=10
30-10=20
10 gallons of 4% butterfat milk should be added to 20 gallons of 1% butterfat milk
