HW help, if you can. Thank you

Jane is interested in buying a car from a used car dealer. Her maximum willingness to pay for the car is $18 (thousand). Bo, the dealer, is willing to sell the car as long as he receives at least $10 (thousand). Thus, there is a potential surplus or gain from trade of $8 (thousand). Jane and the dealer bargain over the transaction price, p. If they cannot agree on a price, then the transaction does not occur, and neither party receives any surplus. If instead, Bo can only get $8 (thousand) elsewhere, then the price that maximizes the Nash product changes by $ thousand. (Enter your response rounded to one decimal place and include a minus sign if necessary.) This change in price is in W favor
