Quizplus · Accepted Answer

To find the marginal product of the second worker, we need to calculate the increase in output when the second worker is added. 
When the first worker produces 5 units and the second worker produces 15 units, the total output is 20 units. 
When the first worker produces 5 units and the third worker produces 25 units, the total output is 30 units. 
Therefore, the marginal product of the second worker is the difference in total output between these two scenarios, which is 10 units. 
So, the answer is B. The best choice is to hire the second worker because they have a positive marginal product, and adding them will increase overall production.
