Question

Which of the following is the cheapest route to visit each city using the "Brute Force Method"
starting from A and ending at A.

Answer 1

Answer:

• ACDBA, $900

Step-by-step explanation:

Since there are 4 cities, there are (4-1)! = 6 possible routes. Half of those are the reverse of the other half, so there are 6/2 = 3 different possible routes. All of those are listed among the answer choices, along with their cost. All you need to do is choose the answer with the lowest cost:

  ACDBA, $900

__

At $960, the other two routes are higher cost.
