9

Step-by-step explanation:

1) Take the sum of the numbers that are before the words "exceed the sum": 19 + 28 + 37 + 46 + 55 + 64 + 73 + 82 + 91 = 495

2) Now, take the sum of the numbers after the words "exceed the sum":

18 + 27 + 36 + 45 + 54 + 63 + 72 + 81 + 90 = 486

3) Finally, take the difference between the two since it's asking for how much the first sum is more than the second sum: 495-486 = 9

the answer would be 150 books

step-by-step explanation:

if you divide 300 by 2 you will get 150
