The following figure shows a firm's marginal and average product curves for labor — the only variable input employed by the firm. The price (wage rate) of labor is $1000 per unit (i.e., w - $1,000). Note that AVC is minimized when AP is maximized. AP, MP 2,700 1.925 1.800 Marginal and average product Average Product Marginal Product 300 450 550 Labor e. (2 points) AVC when 550 units of labor are employed is $_
