To make the cab company's pricing structure a non-proportional situation, they would need to introduce a fixed cost that does not vary with mileage in addition to the per-mile charge.

The correct response is:

Charge a flat rate of $20 and then $12 per mile.

In this case, the $20 flat rate means the total charge will not be directly proportional to the number of miles traveled, breaking the proportional relationship.
