Answer to Question 1

B

Answer to Question 2

The firm compares the cost of hiring an extra worker (the real wage) to the benefit (the extra output produced by an extra worker). Because the firm wants to make a profit, it hires the worker as long as the extra output is greater than the real wage. Thus the firm will demand (hire) the quantity of workers such that the extra output produced by the worker is greater than or equal to the real wage rate. Because labor has diminishing returns, there is some point at which the last worker hired produces just enough output to justify the wage rate and so additional workers will not be hired.
