All I saw there was area so just multiply 10.2 and 17 which is 173.4
The answer to the question is B.
55 - 35 = 20
80 x 0.25 = 20
Therefore, you save money after 80 miles.
First, find the coordinates of all the points.
Then since we're dealing with a scale factor of 1/3 and we're assuming that it is about the origin, all you need to do is divide the coordinates by 3.
ex : (9,3) --> (3,1)
