Rectangle ABCD is dilated by a scale factor of 5 with a center of dilation at the origin. What are the coordinates of the
image of point B'?

Well, through the process of elimination, automatically A and D are off the list, because there aren't 36 yards per inch, or 1 inch per 36 yards, leaving us with B and C. There are 36 inches per yard, but it doesn't make sense to say there is a yard per 36 inches, so B is the right answer.
