Best ResponseYou've already chosen the best response.0So first you can find how much butterfat is in the 50 gallon barrel: \[\frac{x}{50} = \frac{6}{100}\] Once you have x, the amount of butterfat, you know there is 50  x gallons of milk. Then you are trying to calculate a value m such that x / (50  x + m) = (3 / 100). Does that make sense?
