Total Exercise Books Needed
Given:
- Total number of students

- Pages needed per student in a term

The total pages needed for all students:
![$\[\begin{align*}\text{Total pages} &= n * p \\&= 700 * 500 \\&= \boxed{350000}\end{align*}\]$](https://img.qammunity.org/2024/formulas/mathematics/college/z5fosedp270gnzdxmm61py0x9euqqac4fx.png)
Assuming each exercise book contains
pages, the total number of exercise books needed is:
![$\[\begin{align*}\text{Total books} &= \frac{\text{Total pages}}{b} \\&= (350000)/(100) \\&= \boxed{3500}\end{align*}\]$](https://img.qammunity.org/2024/formulas/mathematics/college/vo49und098nwohg5mcfuotuy8jjjl6mz2i.png)
Therefore,
exercise books are needed for the whole term for all students.
