QUANTITY (Thousands of sweaters per day)
In the short run, at a market price of $45 per sweater, this firm will choose to produce 45,000
sweaters per day.
On the preceding graph, use the blue rectangle (circle symbols) to shade the area representing the firm's profit or loss if the market price is $45 and
the firm chooses to produce the quantity you already selected.
Note: In the following question, enter a positive number, even if it represents a loss.
The area of this rectangle indicates that the firm's
would be
thousand per day in the short run.

The following graph shows the marginal cost (MC), average total cost (ATC), and average variable cost (AVC) curves for a typical firm in the industry. For each price in the following table, use the graph to determine the number of jackets this firm would produce in order to maximize its profit. Assume that when the price is exactly equal to the average variable cost, the firm is indifferent between producing zero jackets and the profit-maximizing quantity. Also, indicate whether the firm will produce, shut down, or be indifferent between the two in the short run. Lastly, determine whether it will make a profit, suffer a loss, or break even at each price. Price Quantity Produce or Shut Down? Profit or Loss?
