The third bidder adds three times the value of Harry's, then adds 500 * 3 = $1500. Adding the $1500 to the value of the second bid, the bid is at 1500 + 1000 = $2500. With the final bid of $4000, Harry bids 4000 - 2500 = $1500 more than the third bidder. So the final answer is 1500. <ibo> N'ịgbakwụnye $200 nke Harry n'ọnụ ahịa mbụ ahụ, ọnụ ahịa ya bụ $300 + 200 = $500.
