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?

36,000 initially sold

441,000 sold later with paperback 9 times hardback

so hardback - x
paper back - 9x

total sold = 36,000 + 9x + x = 441,000

10x = 405,000
x= 40,500

paperback = 9x = 4050x9 = 364500
