Explanation:
The computation is shown below:
Year Depreciation Book value
0 $1,200,000
1 $125,000 $1,075,000
2 $125,000 $950,000
3 $125,000 $825,000
4 $125,000 $700,000
5 $125,000 $575,000
6 $125,000 $450,000
7 $125,000 $325,000
8 $125,000 $200,000
The depreciation expense is
= ($1,200,000 - $200,000) ÷ (8 years)
= $125,000
