The figure below shows the supply and the demand for a good (left) and the cost curves of an individual firm in this market (right). Assume that all firms in this market, including the potential entrants, have identical cost curves. Initially, the market is in equilibrium at point A. Cost KV D 6 8 10 12 Quantity Price CATANT 6 MC ATC Quantity efer to the figure above. Suppose that the market has reached the long-run equilibrium. Then, due to news of the product's efects and recall, the demand falls by 2 units at each price. The market will tend toward the new long run equilibrium where

then, plot the supply curve and equilibrium on the second photo
