Let the original price of the book be x. If, after a 33% markup on the initial price, the student had to pay 115.00 for it, then we can calculate x as:
(1 + 33%)(x) = 115
1.33x = 115
x = 115/1.33 = 86.47
This means that the bookstore paid $86.47 for the book.

Answer:
19. 9000
20. 5000
21. 63000
22. 167000
23. 77000
24. 34000
25. 1000
26. 9000
27. 122000
Step-by-step explanation:
To do this, all you need to do is pay attention to the 4th digit and the third. Take 27 for example, 121,619. The fourth digit is 1, and the third digit is 6. because the third digit is 6, the fourth digit gets rounded up to 2. All numbers higher than the fourth digit (fifth, sixth, etc) stay the same and all digits below the fourth digit (first, second, third) become zero. hope this helps!
