Given:
Number of pages in the book = 375
The month of interest = September
The number of pages James needs to read in September per day can be calculated using the formula:
![=\frac{\text{Number of pages in the book}}{Number\text{ of days in the month of September}}](https://img.qammunity.org/2023/formulas/mathematics/college/3m3s0va51abm68dqvig55b2vjuej27yvqw.png)
There are 30 days in the month of September. Hence, the number of pages(n) he needs to read would be:
![\begin{gathered} n\text{ = }\frac{375\text{ pages}}{30\text{ days}} \\ =\text{ }12.5\text{ pages/day} \end{gathered}](https://img.qammunity.org/2023/formulas/mathematics/college/wfphqyqhll6c9dhmv40zs2ha4t0bmd20s5.png)
Hence, the number of pages James needs to read is 12 and a half pages per day.
Answer:
12.5 pages/day
