Answer:
$511,667
Explanation:
The computation of the depreciation expense for 2019 and 2020 is shown below:
= (Purchase price - residual value) ÷ (useful life)
= ($10,500,000 - $2,500,000) ÷ (25 years)
= ($8,000,000) ÷ (25 years)
= $320,000
The depreciation in this method is the same for the rest of the useful life
Now the book value for 2021 would be
= Purchase price - depreciation for 2 years
= $10,500,000 - $320,000 × 2
= $9,860,000
Now the depreciation for 2021 would be
= ($9,860,000 - $650,000) ÷ 18 years
= $511,667
