The company estimates that the monthly demand for the region will be 500,000 gallons of gasoline. Because of the size and speed differences of the trucks, the number of deliveries or round trips possible per month for each truck model will vary. Trip capacities are estimated at 10 trips per month for the Super Tanker, 20 trips per month for the Regular Line, and 30 trips per month for the Econo-Tanker. Based on maintenance and driver availability, the firm does not want to add more than 30 new vehicles to its fleet. In addition, the company has decided to purchase at least 10 of the new Econo-Tankers for use on short-run, low-demand routes. If the company wishes to satisfy the gasoline demand with a minimum monthly operating expense, how many models of each truck should be purchased. Formulate this problem as a LP model. Don't ever try to solve it.
