On January 1, 2018, Northeast USA purchased a used airplane at a cost of $35,200,000. Northeast USA expects the plane to remain useful for eight years (5,000,000 miles) and to have a residual value of $5,200,000. Northeast USA expects the plane to be flown 1,400,000 miles the first year and 1,500,000 miles the second year. Read the requirements Requirement 1a. Compute second-year (2019) depreciation expense on the plane using the straight-line method. Begin by selecting the formula to calculate the company's second-year depreciation expense on the plane using the straight-line method. Then enter the amounts and calculate the depreciation expense for the second year. Cost Residual value )4 Useful life = Straight-line depreciation ( $ 35,200,000 5,200,000 8 3,750,000 Requirement 1b. Compute second-year (2019) depreciation expense on the plane using the units-of-production method. Before calculating the second-year depreciation expense on the plane using the units-of-production method, calculate the depreciation expense per unit. Select the formula, then enter the amounts and calculate the depreciation expense per unit.
