Gullivers Cruises is the only line operating cruises between the islands of Lilliput and Blefuscu, in the South Indian Ocean. Twenty percent of Gullivers potential customers are high-end passengers, who really value good service and are willing to pay a substantial premium for it. The other 80 percent are regular passengers. The cruise line can offer two types of cabin to its passengers: firstclass or economy. The table below describes the willingness to pay for each category of cabin by each type of passenger. The table also presents the marginal costs of each type of cabin for the cruise line. Throughout this question, ignore any sort of capacity constraints faced by Gullivers that is, assume that Gullivers can offer as many cabins of each category as it wants. Also, for simplicity, assume that all cabins are individual, so (i) each passenger buys at most one cabin, and (ii) two or more passengers cannot divide the same cabin. All figures are in dollars. Each type of passenger calculates the net payoff (benefits minus price) that she would get from each cabin and buys the one that would give the higher net payoff, provided that this payoff is non-negative. If both categories of cabin give equal, non-negative net payoffs for a passenger, she buys first-class; if both cabins have strictly negative net payoff for a passenger, she does not buy any of them. Assume that Gullivers wants to maximize its expected profits.

1. Suppose that the cruise line is able to identify the type (high-end or regular) of every potential passenger in the market. Then, the cruise line can choose which category of cabin to offer to each passenger, and at what price. Which category of cabin would Gullivers offer to regular passengers, and what price would it charge for that cabin? What about the high-end passengers?
