5. A cab company charges $12 per mile for a lift to the airport.
What change would the company make to their charges to make this a non proportional situation?
(1 point)
Charge $15 per mile instead of $12
Charge $4 per mile instead of $12
Charge a flat rate of $20 and then $12 per mile
No changes are needed.

To make the situation non-proportional, the cab company would need to charge a flat rate of $20 and then $12 per mile. This would introduce a fixed charge in addition to the charge per mile, making the relationship between the distance and the cost non-proportional. Therefore, the correct answer is: Charge a flat rate of $20 and then $12 per mile.

To determine if the situation is proportional or not, we need to check if the charges vary in direct proportion to the miles traveled.
In a proportional situation, the charges per mile remains constant. In this case, the cab company charges $12 per mile for a lift to the airport. So, to make this a non-proportional situation, we need to change the charges such that they do not remain constant.
Let's check the options given:
1) Charge $15 per mile instead of $12: This is not a non-proportional situation as the charge per mile has increased but still varies proportionally.
2) Charge $4 per mile instead of $12: This is not a non-proportional situation either, as the charge per mile has decreased but still varies proportionally.
3) Charge a flat rate of $20 and then $12 per mile: This option introduces a flat rate fee of $20 in addition to the $12 per mile charge. This change makes the situation non-proportional since the charges no longer vary solely based on the miles traveled. Hence, this is the correct answer.
4) No changes are needed: This option would maintain the original situation with a constant charge of $12 per mile, making it a proportional situation. Therefore, this option is not correct.
So, the company would need to charge a flat rate of $20 and then $12 per mile to make this a non-proportional situation.
