Question

HELP PLEASE!?!?!?!?!?!

Answer 1

The cost is $3.00 for every 2 books.

Explanation:

To calculate the rate (cost per book), we can divide the cost (y) by the corresponding number of books (x):

`(y)/(x)=(6)/(4)=\$1.50\;\sf per\;book`

`(y)/(x)=(9)/(6)=\$1.50\;\sf per\;book`

`(y)/(x)=(12)/(8)=\$1.50\;\sf per\;book`

Therefore, the rate is consistent at $1.50 per book.

Now, to find the cost for every 2 books, we can simply double the rate:

`\sf \$1.50 \;per \;book * 2\; books = \$3.00`

So, the cost is $3.00 for every 2 books.

Note: The points on the graph form a consistent linear pattern, demonstrating that for every 2 books added to the quantity, the cost increases by $3.00.
