Answer
a. $ 30$ dollars.
b. 40 dollars.
c. 60 dollars.
Work Step by Step
a. Use the graph in the exercise. We can find $\lim_{x\to100}f(x)=30$ dollars, which means that the cost to rent the car for the first day and drive 100 miles is 30 dollars.
b. Use the graph in the exercise. As the mileage gets closer to 200, the rental cost approaches 40 dollars.
c. Use the graph in the exercise. The cost to rent the car at the start of the second day is 60 dollars.
