Answer and Explanation:
The computations is shown below;
a) Straight-line method:
= (Original cost - residual value) ÷ (useful life)
= ($360,000 - $10,000) ÷ (5 years)
= ($350,000) ÷ (5 years)
= $70,000
In this method, the depreciation is same for all the remaining useful life
Therefore for first year and second year the same depreciation i.e $70,000 is to be charged separately
(b) Units-of-production method:
= (Original cost - residual value) ÷ (estimated operating hours)
= ($360,000 - $10,000) ÷ (14,000 hours)
= ($350,000) ÷ (14,000 hours )
= $25 per hour
For the first year
= Operating hours in first year × depreciation per hour
= 1,200 hours × $25
= $30,000
And for the second year, it would be
= Operating hours in second year × depreciation per hour
= 2.250 hours × $25
= $56,250
(c) Double-declining balance method:
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 $360,000, so the depreciation is $144,000 after applying the 40% depreciation rate
And, in year 2, the ($360,000 - $144,000) × 40% = $86,400
