Depreciation Methods A machine costing $546,750 was purchased May 1. The machine should be obsolete after three years and, therefore, no longer useful to the company. The estimated salvage value is $20,250. Calculate the depreciation expense for each year of its expected useful life using each of the following depreciation methods: (a) straight-line, (b) double-declining balance. Assume the company has a calendar year end. Do not round any rates. Round final answers to the nearest dollar. Straight-line Year 1 $ 117,000 Year 2 175,500 Year 3 175,500 Year 4 58,500 $ 526,500 DDB $ 243,000 202,500 67,500 13,500 4,490 X
