Question

Quizplus · Accepted Answer

Jerry should make 3 wheels per hour to maximize output. This is because Mandy can make 10 bodies per hour, so Jerry needs to make enough wheels to match her output. He can make 10 wheels per hour, but if he makes 10 wheels per hour, then Mandy will be waiting for wheels to make cars. If he makes 3 wheels per hour, then Mandy will have enough wheels to make cars at her maximum rate of 10 per hour.
