Problem: What if Edwin tells you that he intends to continue drilling at the north site rather than changing to a new site. He complains that he has already spent more than two million dollars on the north site, money which will have been wasted if they change to the south site. Also, there is certainly some chance of finding oil at the north site so it is worthwhile to try and see if they can find it. If that was his entire reasoning process, what would you say about his reasoning? Discuss Edwin's decision making in four sentences or less.
