The average cost of printing a book in a publishing company is c(x) =, <img src="https://tex.z-dn.net/?f=%20%5Cfrac%7B5.5x%2Bk%7
Bogdan [553]
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
