Step-by-step explanation:
3×7+1=22
2×7+8=22
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
Step 4-5 is where Andrew made an error. Since 9.8 is positive, -11.8 + 9.8 = -2. He subtracted 9.8 from 11.8 instead of adding it.
