bija089 [108]

Answer:

3,717,000

Step-by-step explanation:

The calculation of paperback copies is shown below:-

Let us assume hardback copies is x, so paperback copies will be 9x

now the equation is

35,000 + x + 9x = 448,000

10x = 448,000 - 35,000

10x = 413,000

= \frac{413,000}{10}

= 41,300

Therefore, the paperback copies are

=  9\times 41,300

= 3,717,000

Hence, the paperback copies is 3,717,000
