Best ResponseYou've already chosen the best response.0the 100 pounds of cream containing 20% butterfat has 20 pounds of butterfat. if i you add x pounds of 3% butterfat milk it will then contain \[20+.03x\] butterfat. you will have \[100+x\] pounds of milk which you want to be 8% butterfat, so set \[20+.03x=.08(100+x)\] and solve for x
