Answer:
If each sheet of paper were to make 8 pages, then you must multiply 75,000 by 8 to find the total amount of pages will be available to make notebooks.
75,000x8=600,000
Now, each notebook contains 200 pages so you must divide 600,000 by 200 to distribute the pages within the notebooks.
600,000/200=3,000.
In conclusion, 3,000 notebooks can be made from the paper currently available in your problem
