Suppose two hot dog stands, Al’s & Bob’s, position themselves at different ends of a 100 yard stretch of beach. Assume there are 100 beach goers evenly distributed along the stretch of beach and travel costs are $.1 per yard. If Al charges $1 for his hot dogs and Bob charges $2 for his hot dogs, what is the cost of purchasing a hot dog from each stand for a hungry beachgoer situated at a position D yards from Al’s end of the beach? How many consumers will go to Al’s and how many will go to Bob’s?
