Question 3 of 8. Step 1 of 1

Answer 1

308 gallons of 7% and 77 gallons of 2% are needed to obtain the desired 385 gallons.

Combination

Since a dairy needs 385 gallons of milk containing 6% butterfat, to determine how many gallons each of milk containing 7% butterfat and milk containing 2% butterfat must be used to obtain the desired 385 gallons, the following calculation must be performed:

• 385 x 0.06 = 23.1
• 300 x 0.07 + 85 x 0.02 = 22.7
• 310 x 0.07 + 75 x 0.02 = 23.2
• 308 x 0.07 + 77 x 0.02 = 23.1

Therefore, 308 gallons of 7% and 77 gallons of 2% are needed to obtain the desired 385 gallons.
