Answer:
D
Explanation:
Straight line depreciation expense = (Cost of asset - Salvage value) / useful life
($837900 - $81000) / 9 = $84,100
Depreciation expense from 2018 to the end of 2020 would be $84,100
Accumulated depreciation as at 2020 = $252,300
Book value at the beginning of 2021 = $837, 900 - $252,300 = $585,600
remaining useful life as a result of the revision = 5 - 3 = 2
Depreciation expense under the new revisions =
($585,600 - $143000) / 2 = $221,300
