A cab company charges $8 per mile for a lift to the airport, which is proportional since 0 miles cost $0.

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

O Charge $12 per mile instead of $8
O Charge $4 per mile instead of $8
O No changes are needed
O Charge a flat rate of $10 and then $8 per mile
O Charge no flat rate and no $ per mile

The change that would make this a nonproportional situation is:

- Charge a flat rate of $10 and then $8 per mile

This option introduces a flat rate that is not directly proportional to the number of miles traveled.
