Answer:
$25,000 gain
Explanation:
For computing the gain or loss, first we have to determine the depreciation expense so that we can find the book value of an asset
So, under the straight-line method, the depreciation expense would be
= (Original cost - residual value) ÷ (useful life)
= ($450,000 - $50,000) ÷ (8 years)
= ($400,000) ÷ (8 years)
= $50,000
For three years, the depreciation would be
= $50,000 × 3 years
= $150,000
In this method, the depreciation is same for all the remaining useful life
Now the book value would be
= Acquired value of an asset - accumulated depreciation
= $450,000 - $150,000
= $300,000
So, the gain would be
= Sale value - book value
= $325,000 - $300,000
= $25,000
