On January 1, 2020, Monty Company purchased the following two machines for use in its production process. Machine A: The cash price of this machine was $49,500. Related expenditures included: sales tax $3,400, shipping costs $100, insurance during shipping $110, installation and testing costs $90, and $100 of oil and lubricants to be used with the machinery during its first year of operations. Monty estimates that the useful life of the machine is 5 years with a $4,050 salvage value remaining at the end of that time period. Assume that the straight-line method of depreciation is used. Machine B: The recorded cost of this machine was $180,000. Monty estimates that the useful life of the machine is 4 years with a $10,050 salvage value remaining at the end of that time period. Calculate the amount of depreciation expense that Monty 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) Monty uses the straight-line method of depreciation. (2) Monty uses the declining-balance method. The rate used is twice the straight-line rate. (3) Monty uses the units-of-activity method and estimates that the useful life of the machine is 128,750 units. Actual usage is as follows: 2020, 46,000 units; 2021, 36,000 units; 2022, 26,000 units; 2023, 20,750 units.
