Harry Phelps, owner of Harry's Clothing Cupboard, is considering a move from downtown to a new shopping mall. Because he has been downtown for 20 years, and has built up quite a following there. Harry thinks that if he moves, there is a 20% change his business will decline by $100,000, a 30% chance it will remain stable, and a 50% change it will increase by $175,000 because of the quality of sales promotion done by the mall management. Further, the city is considering a downtown revitalization with a plaza in front of Harry's store. He believes there is a 70% change this will pass the city council; if it does, he estimates his business should increase by $200,000. If the plaza is not built, Harry thinks his downtown business will decline about $50,000. Time is of the essence; the mall owners need an answer immediately or he will lose any chance to locate there. Construct a decision tree to help Harry decide on a course of action.
