Answer:
C. $22
Explanation:
We are given a graph showing the relation between the distance travelled in miles by taxi and the taxi fare.
To find an estimate of how much her taxi fare would be if she travelled 8.5 miles by taxi, simply look 8.5 on the x-axis, then trace it upwards till it meets the line. The point where it meets the line would be the corresponding y-value of x = 8.5.
The point would be (8.5, 22). This means, if the woman travels 8.5 miles, her taxi charges would be approximately $22.
