Consider the following graph, which represents the one-way airfare between five cities. A B C D E A * $220 $240 $290 $430 B $220 * $260 $320 $360 C $240 $260 * $180 $300 D $290 $320 $180 * $250 E $430 $360 $300 $250 * Graph the following to represent the information in the table. Use vertices to represent the cities and weights on appropriate edges to show the airfares. Next, assume that you are a salesman who lives in one of the cities (pick any city except for A) and required to fly to all four of the other cities and return to your home city. Describe how you would use the Nearest Neighbor Method to determine the optimal route. What is the total cost for this Hamilton circuit?

A group of friends is represented by the graph below. An edge connecting two names means that the two friends have spoken to each other in the last week. Michael John Steve Erin Stacy Ada (a) Have John and Stacy talked to each other in the last week? O Yes O No (b) How many of the friends in this group has Steve talked to in the last week? friends (c) Among this group of friends, who has talked to the most people in the last week? O Michael O Erin O John O Ada O Stacy O Steve (d) Why would it not make sense for this graph to contain a loop? O A loop would require more than two friends talking at the same time. O A loop would require only one point of origin of calls. O A loop would mean that every friend talked to every other friend in the last week. O A loop would correspond to a friend talking to himself or herself. O A loop would have curves.
