5. Graphing demand for labor and computing the optimal quantity A company operates in a pricetaker market, selling each unit of output for a price of $20 and paying the market wage of $360 per day for each worker it hires. In the following table, complete the column for the marginal revenue product of labor (MRP of labor) at each quantity of workers. Labor Output Marginal Product of Labor Marginal Revenue Product of Labor (Number of workers) (Units of output) (Units of output) (Dollars) 0 0 1 20 20 2 39 19 3 57 18 4 72 15 5 84 12 On the following graph, use the blue points (circle symbol) to plot the firm's labor demand curve. Then, use the orange line (square symbol) to show the wage rate. On the following graph, use the blue points (circle symbol) to plot the firm's labor demand curve.
