4. Fill in the appropriate numbers in the empty cells in the table below. Q Total cost Average cost Marginal cost 0 70 - - 1 200 200 130 2 320 3 153.3 139.9 5. Assume a demand and supply model where the inverse demand is pp = 90 Q? and the inverse supply is ps = Q, where pp is the demand price, ps is the supply price, and Q is quantity. Determine the equilibrium values of p and Q (p* and Q). 6. Assume that a monopoly firm receives a per-unit subsidy of s. The firm's profit equation is m = 24q q* + sq, where 7 is profit and q is output. a. Graph the firm's profit function when s = 0 and when s = 10. Now determine the firm's profit-maximizing level of output for these values of s
