Question

a bookshelf holds 43 books on each shelf is the total number of books proportional to the number of shelves in the bookshelf

Answer 1

If every shelf has the same amount of books, then it can be seen as proportional because one shelf has 43 and 2 have 86, and it keeps going up in a consistent way. 
so 43/1 = 86/2 .

Answer 2

Answer:

Yes, the total number of books is proportional to the number of shelves in the bookshelf.

Step-by-step explanation:

Let y represent total number of books and x represent number of shelves.

We have been given that a bookshelf holds 43 books on each shelf. We are asked to determine whether the total number of books proportional to the number of shelves in the bookshelf.

The total number of books on x shelves would be $43x$. We can represent this information in an equation as:

$y=43x$

Therefore, the total number of books is proportional to number of shelves in the bookshelf and constant of proportionality is 43.
