To represent the situation correctly, we need to account for the total cost of the items purchased by Cheyenne.

Let:
- $ x $ be the cost of one chili cheese dog.

Cheyenne bought:
- 2 milkshakes at $ 3.59 $ each,
- 2 orders of fries at $ 2.79 $ each,
- 2 chili cheese dogs at $ x $ each.

The total cost can be represented as:

\[
2(3.59) + 2(2.79) + 2x = 18.14
\]

or simplified further:

\[
2(3.59 + 2.79 + x) = 18.14
\]

The correct choice from the given options is:

**b) 2(3.59 + 2.79 + x) = 18.14; x represents the cost of one chili cheese dog**

So the correct equation is b), and $ x $ represents the cost of one chili cheese dog.
