if a dairyman has 300 pounds of milk testing 3% butterfat, how many pounds of skimmed milk (with no butterfat) must he remove to have milk testing 3.6% butterfat?"
:
Use this butterfat equation: let x = amt to be removed
:
.03(300) = .036(300 - x)
:
9 = 10.8 - .036x
:
+.036x = 10.8 - 9
:
.036x = 1.8
:
x = 1.8/.036
:
x = 50 lb to be removed
:
:
Check in original equation
.03(300) = .036(300 - 50)
9 = .036(250)
9 = 9
