planes that seat 320 passengers and cost $200 million each, planes that seat 250 passengers and cost $125 million each, and Lockheed planes that seat 275 passengers and cost $200 million each. You are the purchasing manager of an airline company and have a spending goal of $2,900 million for the purchase of new aircrafts to seat a total of 4,480 passengers. Also, you must buy twice as many Lockheed airplanes as Airbus planes. How many of each type of airplane should you order

As Boing is much better in the cost per seat It will purchase from Boing and only to fullfil the requirement

1airbus     320  seat   $     200

18boing         4500  seat   $  2,250

2loockheed    550 seat   $     400

Total               5,370 seat      $  2, 850

Explanation:

Airbus      320 seat   $ 200M

Boeing     250 seat   $ 125 M

Lockheed 275 seat   $ 200 M

We need to get 4,480 seats with a budget of 2,900 millions plus the composition requirement of twice as many Lockheed as Airbus:

Those we will purchase an Airbus and two Lockheed to get the requirement of twice as many Lockheed as Airbus

The rest of the budget will be expended on Boeing
