Hotels operates many hotels throughout the world. Suppose one of its Calgary hotels is facing difficult times because of the opening of several new competing hotels. To accommodate its flight personnel, WestJet has offered International a contract for the coming year that provides a rate of $70 per night per room for a minimum of 50 rooms for 365 nights. This contract would assure International of selling 50 rooms of space nightly, even if some of the rooms are vacant on some nights. Assume zero variable costs. 

The International manager has mixed feelings about the contract. On several peak nights during the year, the hotel could sell the same space for $150 per room. 

1. Suppose the International manager signs the contract. What is the opportunity cost of the 50 rooms on October 20, the night of a big convention of retailers when every nearby hotel room is occupied? What is the opportunity cost on December 28, when only 10 of these rooms would be expected to be rented at an average rate of $100? 

2. If the year-round rate per room averaged $110, what percentage of the 50 rooms in question would have to be rented to make International Hotels indifferent about accepting the offer?
