Pretty simple equation, where we need to find the number of books. If it is 2$ each day per book
72/9 = 8$ per day is the late fee paid
So if each book is 2$, then we can assume
8/2 = 4 books
So equation is
“# books = (amount paid)/(days * per day payment)”
This is what I got I hope it can help you
