Answer:
$0
Step-by-step explanation:
The adjusted basis for any property or assets transferred to a corporation or a partnership in exchange for shares or property rights must be registered at fair market value.
In this case Mr. Brown transferred property with a fair market value of $50,000 and received in exchange stock worth $35,000 and $15,000 in cash. ($50,000 = $35,000 + $15,000)
