Let represent the number of gallons of cream required. Then represents the amount of 2% milk you need to add to get a total of 90 gallons.
There are gallons of pure butterfat in the cream and gallons of pure butterfat in the 2% milk, and once you have 90 gallons of 4% milk you will have 90 times 0.04 = 3.6 gallons of pure butterfat.
