Problem: A monopolist sells in two geographically divided markets, the East and the West. Marginal cost is constant at $50 in both markets. Demand and marginal revenue in each market are as follows:
QE = 900 - 2Pe
MRe = 450 - QE
QW = 700 - PW
MRw = 700 - 2Qw
a. Find the profit-maximizing price and quantity in each market.
b. In which market is demand more elastic?
