A delivery truck driver charges a fixed base price of $6 for 2 miles. After 2 miles, he charges an additional $2 for every mile. After 6 miles, he charges an additional $4 for every mile. Describe the cost of the delivery truck between 1 mile and 2 miles.

Answer:Option B.Step-by-step explanation:It is given that a delivery truck driver charges a fixed base price of $6 for 2 miles. After 2 miles, he charges an additional $2 for every mile and after 6 miles, he charges an additional $4 for every mile. We need to describe the cost of the delivery truck between 1 mile and 2 miles. In the given graph x-axis represents the distance in miles and y-axis represents the cost in dollars. From the given graph it is clear that the value of function is constant between x=1 and x=2. It means the cost of the delivery truck between 1 mile and 2 miles is constant. Therefore, the correct option is B.
