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?
assistant
How many cows does the farmer have? ** The farmer has 125 cows because 50 / .4 = <<50/.4=125>>125
How many female cows does the farmer have? ** The farmer has 75 female cows because 125 x .6 = <<125*.6=75>>75
How much milk will the farmer get a day if he has 75 female cows? ** The farmer will get 150 gallons of milk a day because 75 x 2 = <<75*2=150>>150
