Banana Computer Company sells BananaComputers both in the domestic and foreign markets. Because of the differences in the power supplies, a Banana computer purchased in one market cannot be used in the other market. This means that the company can use third degree price discrimination in order to maximize profits. Let's suppose that it costs $1,000 to produce each computer (this is marginal andaverage cost). Let's suppose further that the domestic and foreign demand curves are given as follows (the subscript "F" denotes "foreign" while the subscript "D" is used to denote "domestic"):

PD=13,000-20QD

PF=17,000-40QF

a.What prices maximize profits for this firm? How many computers do they sell in each market? How much profit does the company earn?

b.Now, suppose that somebody figured out a wiring trick that allows a Banana computer built for either market to be costlessly converted so that it works in the other market. This destroys the company's ability to practice third degree price discrimination and forces them to charge the same price in both markets. What price maximizes the company's profits now? How many computers will they sell in each location? How much profit does the company earn?
