Part 1 of 5 Points: 0.71 of 5 Assume that on September 30, 2020, Swiss, the national airline of Switzerland, purchased an Airbus aircraft at a cost of 49,000,000 (E is the symbol for the euro). Swiss expects the plane to remain useful for nine years (5,500,000 km) and to have a residual value of 5,250,000. Swiss expects the plane to be flown 450,000 km during the remainder of the first year ended December 31, 2020. Compute Swiss's depreciation on the plane for the year ended December 31, 2020, using the following methods: a. Straight-line b. Units-of-production c. Double-diminishing-balance Which method would produce the highest net income for 2020? Which method produces the lowest net income? How does management choose which depreciation method to use? Compute Swiss's depreciation on the plane for the year ended December 31, 2020. (Do not round until the final answer. Then round the depreciation expense to the nearest whole number.) a. The depreciation on the plane for the year ended December 31, 2020, using the straight-line method is
