A cab company charges $12 per mile for a lift to the airport.

Question

What change would the company make to their charges to make this a non proportional situation?

(1 point)

Charge $4 per mile instead of $12

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

Charge $15 per mile instead of $12

No changes are needed

Answer 1

To make the charges a non-proportional situation, the cab company would need to change the way they charge such that the total cost does not consistently maintain a constant ratio to the distance traveled.

The option that would achieve this is:

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

This introduces a fixed fee, which means that the total cost does not vary proportionally with the distance (as the cost starts with a flat fee plus a variable rate based on mileage).
