Question

find how many quarts of 4% butterfat milk and 1 % butterfat milk should be mixed to yield 75% quarts of 2 % butterfat milk.
i have no idea how to even begin this problem...

Answer 1

You need to state the problem correctly. 75 % quarts of 2% butterfat milk makes no sense.

Answer 2

i meant 75 quarts not %...sorry...

Answer 3

Let x = number of quarts of 4% milk to use.
Then 75-x = number of quarts of 1% milk to use.
.04x = butterfat in the x quarts of 4% milk
.01(75-x)= butterfat in the 75-x quarts of 1% milk
.02(75)= butterfat in the final 75 quarts of milk.

So:
.04x+.01(74-x)=.02(75)
Solve it and you will have the number of quarts of 4% milk to use.
