Respuesta :

Part A

According to the information given in the exercise, a bookshelf can hold 54 books. Then, if you want to calculate the number of bookshelves needed to hold 1,728 books, you can make the following Division:

[tex]\frac{1,728}{54}=32[/tex]

Therefore, 32 bookshelves are needed to hold 1,728 books.

Part B

Let be "x" the number of bookshelves needed to hold 1,728 books.

You know that you need 1 bookshelf to hold 54 books. Then, you can set up the following equation to find the value of "x":

[tex]54x=1,728[/tex]

Notice that you set up that "x" bookshelves multiplied by the number of books that 1 bookshelf can hold, is equal to 1,728 books.

Then, if you solve for "x", you get:

[tex]\begin{gathered} x=\frac{1,728}{54} \\ \\ x=32 \end{gathered}[/tex]

Therefore, the answers are:

Part A

[tex]Bookshelves=32[/tex]

Part B

Equation:

[tex]54x=1,728[/tex]
