Answer:
$6,400
Explanation:
The computation of depreciation expense is shown below:-
Rate of Depreciation = 1 ÷ 10 × 2
= 0.2
Depreciation year 1 = Purchased cost × Depreciation percentage
= $40,000 × 20%
= $8,000
Depreciation year 2 = Purchased cost - Depreciation year 1 × Depreciation percentage
= $40,000 - $8,000 × 20%
= $32,000 × 20%
= $6,400
