Question: 40% of a farmer's cattle are males. The rest are females. If a female cow produces 2 gallons of milk a day, how much milk will the farmer get a day if he has 50 male cows?
Answer with step-by-step thinking: The farmer has 125 cows because 50 / .4 = 125. The farmer has 75 female cows because 125 x .6 = 75. The farmer will get 150 gallons of milk a day because 75 x 2 = 150.
So the answer is 150.
