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?

To make this a non-proportional situation, the cab company could introduce a fixed fee in addition to the per mile charge. For example, they could charge $12 per mile plus a base fee of $10 for every ride. This would create a non-proportional relationship between the distance travelled and the cost of the ride.

To make the charges non-proportional, the cab company would need to implement a pricing structure that deviates from a simple, direct relationship between distance and cost per mile. Here are a few possible changes they could make:

1. Implement a flat fee: Instead of charging per mile, the cab company could charge a fixed amount regardless of the distance traveled. For example, they could charge a flat fee of $50 for a ride to the airport, regardless of the distance.

2. Introduce a tiered pricing system: The cab company could establish different price brackets based on mileage ranges. For example, they might charge $12 per mile for the first 10 miles, $15 per mile for the next 5 miles, and $20 per mile for any additional miles beyond that.

3. Consider time-based charges: In addition to the distance traveled, the cab company could factor in the duration of the trip. This could involve charging a higher rate during peak travel hours or adding an extra fee for waiting time at traffic congestion or during pick-up/drop-off.

These examples demonstrate how the cab company can modify their charges to create a non-proportional relationship between distance and cost per mile.

To make the situation non-proportional, the cab company would need to change the rate they charge per mile. In a proportional situation, the cost is directly proportional to the distance traveled. This means that if you travel twice the distance, the cost would be twice as much. To make it non-proportional, the cost per mile would need to change based on factors besides just the distance traveled.

For example, the company could introduce a flat fee in addition to the per-mile rate, or they could implement a pricing structure where the cost per mile decreases after a certain distance.

By incorporating additional factors that affect the fare calculation, such as time of day, traffic conditions, or additional services requested, the company can make the situation non-proportional. This means that the cost per mile would no longer remain constant, and the overall fare would not directly depend on the distance traveled.
