7. Short-run supply and long-run equilibrium
Consider the competitive market for ruthenium. Assume that no matter how many firms operate in the industry, every firm is identical and faces the
same marginal cost (MC), average total cost (ATC), and average variable cost (AVC) curves plotted in the following graph.

The following graph plots the market demand curve for ruthenium.
(?)
Use the orange points (square symbol) to plot the initial short-run industry supply curve when there are 10 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 20 firms. Finally, use the green points (triangle symbol) to
plot the short-run industry supply curve when there are 30 firms.
