The demand for two movies (Joker and The Lighthouse) by rental stores in different parts of London is presented in the table below. The rst column represents the number of stores in each area. Suppose each copy of each movie has a marginal cost of zero. West London East London 40 30 30 South London 20 5 40 a) Suppose the studio sells these two movies separately and can charge a different price in each area. For example, the studio may charge $10 for a copy of the Joker in West London, $20 for a copy of The Lighthouse in East London, etc. What is the optimal price per video? In the remainder of this question, suppose the studio cannot charge a different price in each area. b) Suppose the studio sells movies individually. What prices should the studio charge to maximize profits? c) Suppose the studio sells both movies as a single bundle. What is the optimal price of the bundle? (:1) Now suppose the studio decides to sell movies both individually and as a bundle (\"mixed bundle"). Show that the studio can obtain higher profits with a mixed bundle than only selling movies separately or only selling them as a bundle
