Assume that at the beginning of 2017, US Air purchased a Bombardier Q400 aircraft at a cost of $23,000,000. US Air expects the plane to remain useful for five years (4,450,000 km) and to have a residual value of $5,500,000. US Air expects the plane to be flown 800,000 km the first year, 1,150,000 km each year during years 2 through 4, and 200,000 km the last year. 1. Compute US Air's first-year depreciation on the plane using the following methods: a. Straight-line b. Units-of-production c. Double-diminishing-balance 2. Show the airplane's carrying amount at the end of the first year under each depreciation method. Requirement 1. Compute US Air's first-year depreciation on the plane. a. Using the straight-line method, depreciation is $ . . (Hold all decimals during interim calculations. Round the final solution to the nearest whole b. Using the units-of-production method, depreciation is $ number.) c. Using the double-diminishing-balance method, depreciation is $ . Requirement 2. Show the airplane's carrying amount at the end of the first year under each depreciation method. (Use parentheses or a minus sign when subtracting numbers.)
