Answer:
$41,000
Explanation:
For computing the depreciation expense for 2021, first we have to determine the depreciation expense for 2019 and than book value which are shown below:
Depreciation expense would be
= (Original cost - residual value) ÷ useful life
= ($200,000 - $20,000) ÷ 10 years
= $18,000
Now the book value would be
= Original cost - depreciation expense × number of years
= $200,000 - $18,000 × 2 years
= $200,000 - $36,000
= $164,000
Now the depreciation expense for 2021 would be
= ($164,000 - $0) ÷ 4 years
= $41,000
The four years are come from
= 10 years - 6 years
