To find K, we must use the fact that
 on the day 200 books were printed
 the average cost was $ 9 per book.
 Thus, substituting the values, we have:
 c (x) = (5.5x + k) / (x)
 9 = (5.5 (200) + k) / (200)
 Clearing K
 (200) * 9 = 5.5 (200) + k
 k = (200) * 9 - 5.5 * (200)
 k = 700
 answer
 the value of the constant k is 700

Answer:
To find the scale factor for a dilation, we find the center point of dilation and measure the distance from this center point to a point on the preimage and also the distance from the center point to a point on the image.
