The correct answer is B. charge a flat rate of $20 and then $12 per mile.
In a proportional situation, the rate stays constant regardless of the distance traveled. However, by charging a flat rate of $20 and then an additional $12 per mile, the company is implementing a non-proportional situation where the charges will vary depending on the distance traveled.
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?
A. charge $4 per mile instead of $12
B. charge a flat rate of $20 and then $12 per mile
C. no changes are needed
D. charge $15 per mile instead of $12
