In Example 2 we saw that Airbus A330-300s seat 330 passengers and cost $260 million each, Boeing 767-300ERs seat 270 passengers and cost $220 million each, while Boeing Dreamliner 787-9s seat 240 passengers and cost $290 million each. You are the purchasing manager of an airline company and have a spending goal of $6,090 million for the purchase of new aircraft to seat a total of 6,750 passengers. Your company has a policy of supporting U.S. industries, and you have been instructed to buy twice as many Boeings as Airbuses. Given the selection of three aircraft, how many of each should you order?
