Horizon’s is an airline making decisions about purchasing new airplanes in 2020. They need to decide how many small airplanes to purchase and how many large airplanes to purchase. The

airplane wants their new planes to have a capacity for at least 3,300 people. The airline has

resources for at most 300 hours of maintenance each month. Each small airplane carries 55

people and requires 5 hours of maintenance each month. Each large airplane carries 220

people and requires 10 hours of maintenance each month. Due to demand, Horizon has

decided that their fleet can have no more than 20 new large airplanes. Each small airplane

costs $14,000,000 and each large airplane costs $40,000,000. In order to minimize costs, how

many of each type of airplane should Horizon’s purchase?
