The following table shows the number of cases of water each seller is willing to sell at the prices listed (assume that the same pattern of supply applies at other prices): Price uer case Brook Mountain Cascade Waters Dew Good 0 cases $3.00 100 cases ' zoocases $9.00 soccases (a) If there are only these four suppliers in the market find the aggregate supply at these prices. Assuming that they can supply any number of cases of water (even fractions of a case) and price can be any number, nd a constant c so that the equation Q( = c x P describes market supply. (b) Suppose that market demand is given by Q" = 1200 100P and that supply is as you found in (a). Find the competitive equilibrium. (c) Now suppose that Dew Good drops out of the market. Find the new market supply function as in (a). Find the new equilibrium. (d) What happens to the rms' revenue from the old to the new equilibrium? (e) Use your understanding of the elasticity of linear demand to explain your answer in (d). BONUS: If the price is set at $3 is there excess demand or excess supply in the market when all four firms operate in the market? How much
