1. There are three firms with a cost function (q) = 3* and four firms with a cost function clq) = %qa. We are in the short-run, so no exit or entry takes place. (a) Calculate the market supply function. Hint: You first derive the short run supply function for each type of the firm, and then add up all the supply curves of all firms to obtain the market supply. (b) The market demand is given by Q(p) = 36 /P. Calculate the equilibrium price and quantity. How many units are produced by each type of firm? What are their profits
