You borrow bookcases like the one shown to display 943 books at a book sale. You plan to put 22 books on each shelf. No books will be on top of the bookcases.
To find out how many bookcases you need to borrow to display 943 books, we can divide the total number of books by the number of books that can fit on each shelf.
First, we need to find out how many shelves are required to display 943 books. Since each shelf can hold 22 books, we divide 943 by 22:
943 / 22 = 42.8636
Since we need a whole number of shelves, we can round up to the nearest whole number. In this case, we round up to 43 shelves.
Now, to determine how many bookcases you need, we need to consider that each bookcase can hold some number of shelves (including both the books on the shelves and the empty space above each shelf). Let's assume each bookcase can hold 5 shelves.
To calculate the number of bookcases needed, we divide the total number of shelves (43) by the number of shelves per bookcase (5):
43 / 5 = 8.6
Again, since we need a whole number of bookcases, we round up to 9 bookcases.
Therefore, you would need to borrow 9 bookcases to display 943 books, with 22 books on each shelf and none on top of the bookcases.
