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. DDB 0 Straight-line Year 1 $ 0 $ Year 2 0 Year 3 0 Year 4 0 0 0 0 0 $ 0
