Answer:
a. Kara Lee is the painter so the painting is simply part of her normal business operations in selling it.
Amount is $6,000 and this is a sale.
b. Taxpayer is Reller Gallery who sold the painting as part of their normal business operations.
Profit on Sale = Amount sold - Amount purchased
= 10,000 - 6,000
= $4,000
Amount is $4,000 and the nature is ordinary business income.
c. Lollard Inc sold this painting even though it is not part of their normal operations.
This is therefore a gain.
Gain = 45,000 - 10,000
= $35,000
Amount is $35,000 and is a Capital Gain.
