Question

In a particular city, taxicabs charge passengers $2.20 for entering a cab and then $0.50 for
each one-fifth of a mile (or fraction thereof) traveled. If x represents the distance traveled in miles,
then C(x) is the cost of the taxi fare, where C(x) = $2.20 if x = 0, C(x) = $2.70 if 0<x<0.2, and so on.
The graph of C is shown to the right. Use the graph to find each of the following limits, if it exists.
Select the correct choice below and, if necessary, fill in the answer box to complete your choice.
