Suppose two rms are competing in prices (Bertrand) in an industry
where demand is p=200-4Q.
(a) If both rms have MC=120, what is the equilibrium quantity for each rm? Prots?
(b) Suppose one rm has MC=120 and one has MC=100. Approximately how much prot does each rm make?
(c) Suppose one rm has MC=150 and one has MC=0. Approximately how much prot does each rm make?
