Answer :
Answer:
C)$6,000 gain.
Explanation:
For computing the gain or loss, first we have to determine the depreciation expense for each year which is shown below:
Depreciation per units
= (Original cost - residual value) ÷ (estimated production units)
= ($78,000 - $13,000) ÷ (20,000 units)
= ($65,000) ÷ (20,000 units)
= $3.25 per units
Now for the 2018 year, it would be
= Production units in 2018 year × depreciation per unit
= 500 units × $3.25
= $1,625
For the 2019 year, it would be
= Production units in 2019 year × depreciation per unit
= 3,000 units × $3.25
= $9,750
For the 2020 year, it would be
= Production units in 2020 year × depreciation per unit
= 3,500 units × $3.25
= $11,375
For the 2021 year, it would be
= Production units in 2021 year × depreciation per unit
= 1,000 units × $3.25
= $3,250
Now the accumulated depreciation would be
= $1,625 + $9,750 + $11,375 + $3,250
= $26,000
Now the book value would be
= Acquired value of an asset - accumulated depreciation
= $78,000 - $26,000
= $52,000
So, the gain would be
= Sale value - book value
= $58,000 - $52,000
= $6,000 gain
