Compute the depreciation expense under straight-line method for 2022. Compute the depreciation expense under units-of-activity for 2022, assuming machine usage was 1,630 hours. (Round intermediate calculations to 1 decimal place, e.g.10.1 and final answer to 0 decimal places, e.g. 2,125.) Compute the depreciation expense under declining-balance using double the straight-line rate for 2022 and 2023
