Calculate the amount of depreciation expense that Bridgeport 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 O decimal places, e.g. 2,125.) (1) Bridgeport uses the straight-line method of depreciation. (2) Bridgeport uses the declining-balance method. The rate used is twice the straight-line rate. (3) Bridgeport uses the units-of-activity method and estimates that the useful life of the machine is 135,880 units. Actual usage is as follows: 2022, 54,000 units; 2023, 39,000 units: 2024, 24,000 units: 2025, 18,880 units, Straight- line $ method Declining- balance $ method Units-of- activity method 2022 $ Depreciation Expense 2023 2024 $ $ $ $ 2025
