6. Deriving the short-run supply curve

Consider the competitive market for sports jackets. 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.
 
Suppose there are 7 firms in this industry, each of which has the cost curves previously shown.
On the following graph, use the orange paints (square symbal) to plat points alang the portion of the industry's short-nun supply curve that
correspands to prices where there is positive output. (Note: You are given more points to plot than you need.) Then, place the black paint (plus
symbol) on the graph to indicate the shart-run equNbrium price and quantity in this market.
Note: Dashed drop lines will automatically extend to both axes.

QUANTITY (Thousands of jackets)
For each price in the following table, use the graph to determine the number of jackets this fArm would produce in arder to maximize its prafit. Assume
that when the price is exactly equal to the average varlable cost, the firm is indiferent between producing zero jackets and the profit-maximizing
quantity. Also, Indicate whether the firm will produce, shut down, or be indiferent between the two in the short run. Lastly, determine whether it will
make a profit, suffer a loss, or break even at each price.
