Assume that on September 30, 2015, LuxAir, an international airline based in Germany, purchased a Jumbo aircraft at a cost of €42,500,000 (€ is the symbol for the euro). LuxAir expects the plane to remain useful for five years (5,000,000 miles) and to have a residual value of €5,200,000. LuxAir will fly the plane 350,000 miles during the remainder of 2015. Compute Lux Air's depreciation on the plane for the year ended December 31, 2015, using the following methods:
a. Straight-line
b. Units-of-production
c. Double-declining-balance
Which method would produce the highest net income for 2015? Which method produces the lowest net income?
