Comparing three depreciation methods Dexter Industries purchased packaging equipment on January 8 for $108,000. The equipment was expected to have a useful life of three years, or 27,000 operating hours, and a residual value of $5,400. The equipment was used for 10,800 hours during Year 1, 8,100 hours in Year 2, and 8,100 hours in Year 3. Required: 1. Determine the amount of depreciation expense for the three years ending December 31, by (a) the straight-line method, (b) the units-of-activity method, and (c) the double-declining-balance method. Also determine the total depreciation expense for the three years by each method. Round the final answers for each year to the nearest whole dollar Depreciation Expense Units-of-Activity Method Year Straight-Line Method Double-Declining-Balance Method Year 1 4 Year 2 4 Year 3 4 Total 2. What method yields the highest depreciation expense for Year 1? 3. What method yields the most depreciation over the three-year life of the equipment
