| Calculate the amount of depreciation expense that Concord should record for Machine B each year of its useful life under the following assumptions. (Round depreciation cost per unit to 2 decimal places, e.g. 12.25. Round final answers to 0 decimal places, e.g. 2,125.) (1) | | Concord uses the straight-line method of depreciation. | (2) | | Concord uses the declining-balance method. The rate used is twice the straight-line rate. | (3) | | Concord uses the units-of-activity method and estimates that the useful life of the machine is 141,500 units. Actual usage is as follows: 2020, 49,500 units; 2021, 39,000 units; 2022, 28,500 units; 2023, 24,500 units. | | | Depreciation Expense | | | 2020 | | 2021 | | 2022 | | 2023 | Straight-line method | | $ | | $ | | $ | | $ | Declining-balance method | | $ | | $ | | $ | | $ | Units-of-activity method | | $ | | $ | | $ | | $ | | | | |
