The inverse demand curves for the domestic and foreign markets are expressed as follows: Domestic: Pd = 100 - 15Q Foreign: Pf=60 - 2.5Q The estimated total production costs are given by C = 10,800 + 20Q + 0.10Q2 What is the corresponding marginal cost equation? a) What are the corresponding marginal revenue and demand equations for the two markets? b) What is the total profit-maximizing level of output? c) How much should be sold to each market? d)What prices should be charged in each market?
