Answer:
A. $17,280.
Explanation:
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 2017, the original cost is $120,000, so the depreciation is $48,000 after applying the 50% depreciation rate
And, in year 2018, the ($120,000 - $48,000) × 40% = $28,800
And, in year 2019, ($120,000 - $48,000 - $28,800) × 40% = $17,280
Hence, the first option is correct
