Answer:
Danny's BATNA is $15,000
Explanation:
BATNA means best alternative to a negotiated agreement.
Is the option available to a decision maker outside any agreement already reached in a business transaction.
In the scenario,the best alternative to negotiated agreement of Danny selling the car for at least $16,000 is to accept $15,000 offered by another friend.
Even though the blue book prices showed that the car was worth $18,500,no buyer is coming forth with such negotiated price,hence the BATNA for Danny is $15,000
