First, we can say that the number of pages Y that Jared has read after 5 days is:
Y = 85 + 5x
Where x is the number of pages that he will have to read every day.
Now, we know that the total number of pages is 300, so replacing y by 300, we get:
300 = 85 + 5x
So, solving for x, we get:
[tex]\begin{gathered} 300-85=5x \\ 215=5x \\ \frac{215}{5}=x \\ 43=x \end{gathered}[/tex]Therefore, Jared will have to read 43 pages per day.
Answer: 43 pages
