The equation should be
36000+H+9H=441000 Where H=hardback copies
So H=40500 and Paperback copies(P) = 9*40500 = 364,500
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?
Thought this was an easy one but i guess not coz my answer E doesn't match the official answer C.
used this to arrive at E.
where h = hardcover copies sold after they started selling paperbacks
