Given:

2002 sold 1000 paperback books and 1500 hardback books for a total of 2,500 books.

2003 sold 15% more paperback books and 5% more hardback books.

1000 x 1.15 = 1,150 paperbacks

1500 x 1.05 = 1,575 hardbacks

1150 + 1575 = 2,725

2,725 - 2,500 = 225

225 / 2,500 = 0.09

0.09 x 100% = 9% choice C
