Calculate the amount of depreciation expense that Bramble 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) Bramble uses the straight-line method of depreciation. (2) Bramble uses the declining-balance method. The rate used is twice the straight-line rate. (3) Bramble uses the units-of-activity method and estimates that the useful life of the machine is 148,000 units. Actual usage is as follows: 2020, 51,500 units; 2021, 41,000 units; 2022, 30,500 units; 2023, 25,000 units.
