Answer:
There are 18 books per box
Step-by-step explanation:
It is about a division problem.
Division consists in splitting a set of elements into equal parts.
In this case, Jori has to fill each box with the same number of books.
The division will show the exact number of books per box as shown:
\(book\, per\, box = \frac{126\, books}{7\, boxes}=18\, books\, per\, box\)
So, there are 18 books per box
