Consumer Choice and Demand: Suppose Karen is planning a trip to Hawaii. Her research indicates that the average price of a hotel room is $250 per night. Karen calls one hotel and they tell her that they are offering a special rate for rooms on the thirteenth floor. Karen is deeply superstitious and knows that staying on the thirteenth floor will cause her to experience negative utility. What is the maximum amount that Karen should pay for a room on the thirteenth floor? Now suppose that Karen books a room at a different hotel, but upon checking in they tell her there are only rooms available on the thirteenth floor. She paid $250 a night for the room and it is non-refundable. However, there is a hotel across the street where she can pay for a room on the tenth floor.
