(2 marks) Suppose home government in country B imposes a restriction that the monopolist cannot sell more in the export market. That is: QASQB must hold. However, the monopolist can charge two different prices in countries A and B. Find the amount of output that monopolist sells in each country and the resulting price levels (which will be different for A and B) that maximizes the monopolist's joint profits (i.e., the sum of profits in the two countries)
