Answer:
a. $9,000
b. $22,000 and $11,000
c. $5,220 and $6,660
Explanation:
The computation of the depreciation expense for the two years are shown below:
a) Straight-line method:
= (Original cost - residual value) ÷ (useful life)
= ($44,000 - $8,000) ÷ (4 years)
= ($36,000) ÷ (4 years)
= $9,000
In this method, the depreciation is same for all the remaining useful life
So, in year 2021 and 2022, the depreciation expense would be $9,000
(b) Double-declining balance method:
First we have to find the depreciation rate which is shown below:
= One ÷ useful life
= 1 ÷ 4
= 25%
Now the rate is double So, 50%
In year 2021, the original cost is $44,000, so the depreciation is $22,000 after applying the 50% depreciation rate
And, in year 2022, the $22,000 × 50% = $11,000 . The $22,000 is come from $44,000 - $22,000
(c) Units-of-production method:
= (Original cost - residual value) ÷ (estimated production)
= ($44,000 - $8,000) ÷ (20,000 hours)
= ($36,000) ÷ (20,000 hours
= $1.8 per hours
For the 2021, it would be
= Production hours in 2021 year × depreciation per hour
= 2,900 hours × $1.8
= $5,220
Now for the 2022 year, it would be
= Production hours in 2022 year × depreciation per hour
= 3,700 hours × $1.8
= $6,660
