Answer:
Barry Company must recognize a $5,000 gain resulting fro the disposal of the patent.
Explanation:
the patent's book value = acquisition cost - accumulated amortization = $120,000 - $100,000 = $20,000
gain from disposal of patent = selling price - book value = $25,000 - $20,000 = $5,000
Since patents are intangible assets, they are amortized, not depreciated. But accumulated amortization works in the same way as accumulated depreciation, they both reduce the asset's carrying value.
