Final answer:
The correct answer is C, r = m + 22. The rental car company charges $20 to rent a car plus $2 per mile driven.
Step-by-step explanation:
The correct answer is C,r=m+22.
The rental car company charges $20 dollars to rent a car plus $2 dollars per mile driven. This can be represented by the equation r = 20 + 2m, where r is the total cost and m is the number of miles driven.
To calculate the total cost for renting a car, you would substitute the number of miles driven into the equation. For example, if a customer drives 10 miles, the total cost would be 20 + 2(10) = 20 + 20 = $40.
