23. A competitive rm receives a price of $3 for each unit of output (Q) and must pay $21 an hour to each worker; workers are the only variable input to production. Complete the following table (where MPL is the marginal product of labor, and TR is total revenue): Workers Q/hour w Price Value MPL Wage Rate TR/hour Total Wages Prot 0 0 - 1 11 2 20 3 27 4 32 5 35 What is the rule a prot-maximizing rm uses to decide how many workers to hire? Therefore, how many workers should the rm hire? How much output will the rm produce per hour? How much total revenue will the rm bring in? If xed costs are zero, how much prot would the rm earn? Is this rm in a long-run equilibrium? Graph VMPL, labeling everything relevant. What are on the axes? Now graph the wage rate. At What quantity do these lines cross, and what does this tell you
