Chapter 12.1, Problem 13E

Global Air Lines has contracted with a tour group to transport a minimum of $1,600$ first-class passengers and $4,800$ economy-class passengers from New York to London during a $6$ month time period. Global Air has two types of airplanes, the Orville $606$ and the

Wilbur W- $1112$. The Orville $606$ carries $20$ first-class passengers and $80$ economy-class passengers and costs $\$12,000$ to operate. The Wilbur W- $1112$ carries $80$ first-class passengers and $120$ economy-class passengers and costs $\$18,000$ to operate. During the time period involved, Global Air can schedule no more than $52$ flights on Orville $606$ s and no more than $30$ flights on Wilbur W- $1112$ s. How should Global Air Lines schedule its flights to minimize its costs? What operating costs would this schedule entail?
