If there were 20 firms in this market the short run equilibrium would be $___ per pound. At this price firms in the industry would _____. Therefore in the long run firms would _____ the titanium market. Because you know that competitive firms earn ___ economic profit in the long run , you know the long run equilibrium Price must be $__ per pound. From each graph you can see that this means there will be __ firms operating in the titanium industry and long run equilibrium. True or false assuming implicit cost are positive each of the firms operating in industry in the long run earns negative accounting profit.
Consider the competitive market for titanium. Assume that, regardless of how many firms are in the industry, every firm in the industry is identical
and faces the marginal cost (MC), average total cost (ATC), and average variable cost (AVC) curves shown on the following graph.

Use the orange points (square symbol) to plot the initial short-run industry supply curve when there are 20 firms in the market. (Hint: You can
disregard the portion of the supply curve that corresponds to prices where there is no output since this is the industry supply curve.) Next, use the
purple points (diamond symbol) to plot the short-run industry supply curve when there are 30 firms. Finally, use the green points (triangle symbol) to
plot the short-run industry supply curve when there are 40 firms.
