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.
