Quizplus · Accepted Answer

Riva can produce 4 cases alone and with the help of Atul they can produce 7 cases, so Atul's contribution is 3 cases (7-4). Therefore, Atul's marginal product is 3 cases. 
The best choice is to hire Atul because his contribution will increase the total output of hard cider.
