Final answer:
To find the number of books per box, divide the total number of books by the number of boxes. In this case, Jori has 7 boxes of books and a total of 126 books. Therefore, there are 18 books per box.
Step-by-step explanation:
To find how many books are there per box, we need to divide the total number of books by the number of boxes. In this case, Jori has 7 boxes of books and a total of 126 books. So, we can divide 126 by 7 to find the number of books per box:
The student is asking how many books are there per box if Jori has seven boxes of books in total and there are 126 books. To find the number of books per box, we divide the total number of books by the number of boxes.
Number of books per box = Total number of books / Number of boxes
Number of books per box = 126 / 7
Number of books per box = 18 books per box
