Step-by-step explanation:
combine like terms in PEMDAS order. Add 4, 9, and 7, then, subtract 11.
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
