May I get some help with D please

Computing Partial Period Depreciation under Multiple Depreciation Methods To demonstrate the computations involved in several methods of depreciating a fixed asset, the following information is provided. Cost and residual value Estimated service life Acquisition cost $37,500 Years 5 Residual value $1,500 Service hours 30,000 Productive output (units) 72,000 Required Compute the annual depreciation using each of the following methods assuming that the asset was purchased on August 1, 2020. a. Straight-line depreciation: Compute the annual depreciation rate and amount for each year. Depreciation rate: 0.2 2020 2021 2022 2024 2025 3,000 $ 7,200 $ 7,200 $ 7,200 $ 7,200 $ 4,200 2023 $ b. Units-of-production method using service hours as a measure of input: Compute the depreciation rate and amount for the first partial year assuming 2,700 service hours of actual operation. Depreciation rate: 1.2 2020 3,240 C. Units-of-production method using units produced as a measure of output: Compute the depreciation rate and amount for the first partial year assuming 5,400 units of output. Depreciation rate: 0.5 2020 2,700 $ d. Sum-of-the-years'-digits method: Compute the depreciation amount for each year. 2020 2021 2022 2023 2024 2025 $ 36,000 X $ 10,800 x $ 8,400 x $ 6,000 x $ 3,600 x $ 1,200 X e. Double-declining balance method: Compute the depreciation amount for each year. 2020 2021 2022 2023 2024 2025 6,250 $ 12,500 $ 7,500 $ 4,500 $ 2,700$ 945 X
