There were 36.000 hardback copies of a certain novel sold before the paperback version was issued. From the time the first paperback copy was sold until the last copy of the novel was sold. 9 times as many paperback copies as hardback copies were sold. If a total of 441.000 copies of the novel were sold in all, how many paperback copies were sold?

(A) 45.000
(B) 360.000
(C) 364.500
(D) 392.000
(E) 396.900

I make it C

441,000 (total sold) – 36,000 (hardbacks sold prior to issue of paperback) = 405,000 (total sold from issue of paperback - hardback and paperback combined.

9 times the amount of hardbacks were sold in paperback

Thus 9x (paperbacks) + x (hardbacks since issue of paperbacks) = 405,000

Thus x = 40,500

Thus 9x (number of paperbacks sold) = 364,500

Does that seem right?

OA?
