Stan read an ad in the newspaper which said that the jackpot for picking the six winners in the dog race on the last night of the season was $825,000. Stan went that night and correctly picked the winners. However, it turned out that the newspaper had made a mistake. The jackpot was $25,000, not $825,000. Therefore the track owners refused to pay the latter amount. If this ad is treated like offers of reward,can Stan collect the $825,000?
