A price- discriminating monopolist sells a good in 2 markets, and he is only Capable of doing simple per-unit pricing in each market.

The firm's total cost is of producing 21, 22 in the two ( Etz2 ) a) what are the profit-maximizing quantities 9,, 92 in the two markers? b ) what are the profit-maximizing prices PI, PZ in the two markers? ( ) suppose that the monopolist is now restricted to change the same Price in the two markets, what would be the market demand for this combined market ? Assume that the two markets have the same size ( normalized to ! ) d ) Following port c, what is the objective function of the monopolist who now carrot do third-price discrimination ?
