Assume that on September 30, 2017, EuroAir, an international airline based in Germany, purchased a Jumbo aircraft at a cost of €45,000,000 (€ is the symbol for the euro). EuroAir expects the plane to remain useful for four years (4,000,000 miles) and to have a residual value of €6,000,000. EuroAir will fly the plane 350,000 miles during the remainder of 2017. Compute EuroAir’s depreciation on the plane for the year ended December 31, 2017, using the following methods:

a. Straight-line

b. Units-of-production

c. Double-declining-balance

Which method would produce the highest net income for 2017? Which method produces the lowest net income?
