Answer:
The answer is C
Explanation:
The formula for straight-line depreciation is:
(Cost of the asset minus salvage value) ÷ number of useful life.
Cost of the asset is $12,000
Salvage value is $2,000
Number of useful life is 5 years.
Therefore, we have:
($12,000 - $2,000) ÷ 5
= $2,000.
Accumulated depreciation balance at the end of the third year is $6,000($2,000 x 3).
So the net book value of the asset at the beginning of fourth year is $6,000($12,000 - $6,000)
The new salvage value is $1,200 and the number of year has changed to 6 years.
3 years have has been used. So the new useful life will be 3 years (the new 6 years minus the 3years that has gone).
We now have:
($6,000 - $1,200) ÷ 3 years
$1,600 as the new depreciation
