Susan recorded the cumulative number of miles she ran over several days on the following graph.

Which of the following would be the best prediction for the value of the independent variable for when Susan has run a total of 64 miles.

A. 42 days
B. 64 days
C. 128 days
D. 32 days.

Answer 1

Answer: Hey there,

I believe your answer is C) 128 days.

Explanation:

Reason-

As you can see on the graph the number of days running is exactly doubled on the graph.

So because she ran 64 days you would just double that number: 64*2=126

Thus you end up with 128 days or letter C.

Hope this helps!
