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

Let x = number of quarts of 4% milk to use. Then 75x = number of quarts of 1% milk to use. .04x = butterfat in the x quarts of 4% milk .01(75x)= butterfat in the 75x quarts of 1% milk .02(75)= butterfat in the final 75 quarts of milk. So: .04x+.01(74x)=.02(75) Solve it and you will have the number of quarts of 4% milk to use.

Do you remember when I wrote that x = the amount of 4% milk to use and that 75x = the amount of 1% milk to use.?

yes

so it should be 1x instead of 4x? so 1x+1(75x02(75)?

sorry. 1x+1(75x)=2(75) ?

So x = 25 and x is the amount of 4% milk to use. 75x=7525=50 and 75x is the amount of 1% milk to use.
