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 436,000 copies of the novel were sold in all, how many paperback copies were sold?	Answers:
A) 45,000  B) 360,000  C) 364,500  D) 392,000  E) 396,900
Say x was the # of hardback copies sold from the time the first paperback copy was sold.   Then the total # of paperback copies sold was 9x;   Hence the total # of copies sold was (hardback)+(paperback)=(36+x)+(9x)=436 --&gt; x=40.   So, the total # of paperback copies sold was 9x=9*40=
