2. Suppose Delta Airlines buys a Boeing 777-9 for $500 million. The airplane lasts for 25 years and then must be scrapped, with no salvage value. Assume it depreciates uniformly by $20 million a year. If Boeing had not bought the airplane, it could have invested in projects earning 10 percent per year. What is Boeing's user cost of capital for the aircraft in the eleventh year after its purchase (i.e., after ten years)?
