Answer and Explanation:
The computation of the depreciation expense for the first year is shown below:
1) Straight-line method:
= (Original cost - residual value) ÷ (useful life)
= ($16,000 - $1,600) ÷ (4 years)
= ($14,400) ÷ (4 years)
= $3,600
In this method, the depreciation is same for all the remaining useful life
(2) Double-declining balance method:
First we have to calculate the depreciation rate which is given below:
= One ÷ useful life
= 1 ÷ 4
= 25%
Now the rate is double So, 50%
In year 1, the original cost is $16,000, so the depreciation is $8,000 after applying the 50% depreciation rate
(c) Activity based method:
= (Original cost - residual value) ÷ (estimated production)
= ($16,000 - $1,600) ÷ (15,000 hours)
= ($14,400) ÷ (15,000 hours)
= $0.96 per hour
Now for the first year, it would be
= Production hours in first year × depreciation per hour
= 2,100 hours × $0.96
= $2,016
