Answer:
$21,600
Step-by-step explanation:
The computation of the total amount of depreciation to be expense is shown below:
First, we have to find the depreciation rate which is shown below:
= One ÷ useful life
= 1 ÷ 5
= 20%
Now the rate is double So, 40%
In year 1, the original cost is $90,000, so the depreciation is $36,000 after applying the 50% depreciation rate
And, in year 2, the $(90,000 - $36,000) × 40% = $21,600
Residual value is ignored in this method.
