The sales representative has two options: 1) A-E-C-F-A and 2) A-E-F-C-A. Now let’s compare the costs of these two options:

Option 1: A-E-C-F-A

From A to E the cost is 7 dollars. From E to C it’s 2 dollars. From C to F it’s 4 dollars. From F to A it’s 3 dollars. The total spent is 16 dollars.

Option 2: A-E-F-C-A

From A to E the cost is 7 dollars. From E to F it’s 6 dollars. From F to C it’s 4 dollars. From C to A it’s 3 dollars. The total spend is 20 dollars.

We see that option 1 is cheaper, and the cost is 16 dollars.

Answer: C

(A) $13
(B) $14
(C) $16
(D) $18
(E) $20

Look at the image below:



The distance from A to D is 2.
The distance from B to E is 5.
The distance from F to E is 6.
...

Does this make sense?
