Juan needs 10 half-gallons of milk to bake 40 cookies with. How many half-gallons of milk does Juan need to bake 200 dozen cookies? Give me reasons, before answering the question
If 10 half - gallons of milk bake 40 cookies, then one half - gallon of milk bakes 40 / 10 = 4 cookies. If one half - gallon of milk bakes 4 cookies. to bake 200 cookies, you'll need 200 / 4 = 50 half - gallons of milk. So the final answer is 50.
