QUS = 48, 000 - 600PUS;
QHK = 42, 000 - 300PHK,
where all prices are in expressed US dollars.
1) What conditions must be satisfied for SAR Publisher to practice price discrimination between the two markets?
2) Assume that the conditions you described in part (a) are satisfied. What price will SAR Publisher charge its textbook in each market, assuming there is no shipping cost?
