2- David likes to eat lunch at local restaurants however, in selecting a restaurant he uses three criteria. First is to minimize the amount of travel time, which means that close-by restaurants are preferred on this attribute. The next objective is to minimize cost, and David can make a judgment of the average lunch cost at most of the restaurants that would be considered. Finally, variety comes into play. On any given day, he would like to go somewhere different from where he has been in the past week. Assume that, today is Monday, his first day back from a two-week vacation, which means variety, is not important for him. Therefore, David considers distance and price to be equally important, where should he go today for lunch?
