Congratulations. You've been hired as the manager of an A+ Rental Cars franchise that serves a small southern city. A+ is located at a regional airport, and 40% of their customers are travelers, with the remaining coming from the town (which has a small college and a solar panel production facility). The airport is a good location for the business, as it is located very close to the college campus, and about a 10-minute drive into the center of town (which can also be reached by taxi or bus). You have a fleet of 72 cars on site (47 'economy' cars and 25 'luxury' cars). Additional cars can be delivered from A+ Rental Cars' corporate hub, approximately 70 miles away, if demand for a particular vehicle type exceeds the number of cars you have available. Alternatively, a customer renting an economy car can be upgraded at no charge to a luxury car, if demand exceeds availability for economy cars. There is one local competitor, Discovery Rent-a-Car, also located at the airport. They have a slightly different system of car categories: Sub-Compact, Compact, Mid-Sized, and Large
