I have this problem about account record pagination. I have to write the function that describes the total pages needed to contain those account records.

This is the problem:

# Account record quantity to store per page per_page € R  # Account records to insert in pages tot_acc € R   # The total pages needed to store the `tot_account` quantity f(per_page,tot_acc) = tot_page € R = ?  

I need to find f(per_page,tot_acc).

Are you asking something like:

With all variables as integers, given the first page number of a set of accounts $i$, the number of accounts that can fit on a page $d$, the total number of accounts $n$, what is the number of the last page?

If so, then you need to use $\left\lceil \frac{n}{d}\right\rceil$ pages for the accounts where the brackets mean ceiling i.e. round up to the next integer. You need to add that to the page before the starting point $i-1$ to give the final page of the accounts $f(i,d,n) = \left\lceil \frac{n}{d}\right\rceil + i -1$ or if you prefer $\text{tot_page} = f(\text{page, per_page, tot_acc}) = \left\lceil \frac{\text{tot_acc}}{\text{per_page}}\right\rceil + \text{page} -1.$

Perhaps you were asking something else.
