Answer:
Book value at point of revision = $54,640
Remaining depreciable cost = $54,640
Depreciation per year for years 2 and 3 = $28,320
Step-by-step explanation:
Depreciation expense using the straight line depreciation method = ( Cost of asset - Salvage value) / useful life
Depreciation expense before the revision = ($67,800 - $2000) / 5 = $13,160
Book value at point of revision = $67,800 - $13,160 = $54,640.
Depreciation expense after the revision = ($54,640 - $2000) / 2 = $28,320
