Q. The long-run average cost curve for a firm in an industry is:
ATC = 10Q2 - 50Q + 100, as well as its marginal cost is:
MC = 30Q2 - 100Q + 100.
Market Demand as well as is given by:
Qd = 9000 - 200Pmkt

b) What is the market equilibrium cost?
c) What is the equilibrium number of firms in the market?
