Need some help on this study guide question I must provide all calculations. Thanks for any help!

1) Abe Simpsons Historical Aircraft, Inc. (ASHAI) is considering adding a rare World War II B-24 bomber to its collection of vintage aircraft. The plane was forced down in Burma 1942, and it has remained there ever since. Flying a crew to Burma and collecting the wreckage will cost $100,000. Transporting the parts to the companys restoration facility in Springfield will cost another $35,000. Restoring the plane to flyable condition will cost an additional $600,000 at t₀.

ASHAIs operating costs will increase by $40,000 a year at the end of years 1 through 7. At the end of years 3 through 7, revenues from exhibiting the plane at airshows will be $70,000. At the end of year 7, the plane will be retired. At that time the plane will be sold to a museum for $500,000.

The plane falls into the 7 year MACRS depreciation schedule. ASHAIs tax rate is 35% and the companys required return on the project is 12%. Calculate the NPV and IRR of the proposed investment in the plane.
