Problem 10-03A a-c On January 1, 2020, Swifty Company purchased the following two machines for use in its production process. Machine A: The cash price of this machine was $52,000. Related expenditures included: sales tax $3,100, shipping costs $200, insurance during shipping $120, installation and testing costs $50, and $150 of oil and lubricants to be used with the machinery during its first year of operations. Swifty estimates that the useful life of the machine is 5 years with a $5,500 salvage value remaining at the end of that time period. Assume that the straight-line method of depreciation is used. The recorded cost of this machine was $180,000. Swifty estimates that the useful life of the machine is 4 years with a $10,200 salvage value remaining at the end of that time period. Machine B: Calculate the amount of depreciation expense that Swifty 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) (2) (3) Swifty uses the straight-line method of depreciation. Swifty uses the declining-balance method. The rate used is twice the straight-line rate. Swifty 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, 49,000 units; 2021, 39,000 units; 2022, 29,000 units; 2023, 24,500 units. Which method used to calculate depreciation on Machine B reports the highest amount of depreciation expense in year 1 (2020) ? Depreciation Expense 2021 2022 2020 2023 Straight-line method U A The highest amount in year 4 (2023)? Declining-balance method U A Units-of-activity method A A
