A bookstore orders 200 books the books are packaged in boxs that hold 24 books each all the boxs the bookstore receives are full
faust18 [17]

Answer: The bookstore  receive 9 boxes.

Step-by-step explanation:

Hi, to answer this question we have to divide the number of books (200) by the number of books that each box contains (24 if it is full).

Mathematically speaking:

200 /24= 8.3333333

This means that the bookstore receives 8 full boxes and 1 box that isn't full.

8 x 24 = 192 books

200 -192 = 8 books (the 9th box will contain 8 books)

In conclusion, the bookstore  receives 9 boxes.
