Answer:
$24,000
Step-by-step explanation:
From the time an asset is acquired until the time it is sold, an asset experiences a number of events which causes an increase or decrease of its total value. Th adjusted basis of a given asset, takes the base price of an asset and adjusts it for changes in value reflecting enhancements and or depreciation. For instance, a given asset purchased for $100, depreciates by $10 and has an improvement of $60 would have an adjusted basis of $100 - $10 + $60 = $150.
Now when Mary bought her furniture, the adjusted basis was $20,000. At the time of exchange, the fair market value of the furniture is $4,000 whereas Mary also gave $4,000 to the dealer in the transaction. This $4,000 changes the value ans is added to the previous adjusted basis of $20,000.
Mary's adjusted basis in the new furniture after the exchange is:
= $4,000 + $20,000
= $24,000
