for $72,000. The equipment was expected to have a useful life of three years, or 18,000 operating hours, and a residual value of $4,500. The equipment was used for 7,600 hours during Year 1, 6,000 hours in Year 2, and 4,400 hours in Year 3. INSTRUCTIONS 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 doubledeclining-balance method 2. Determine the total depreciation expense for the three years by each method. What method yields the highest depreciation expense for Year 1? 3.
