Solution

The correct table that represents the relationship between the number of books and the total price is Table B.

Here's why:

In the problem, it is stated that 2 books cost 19.50.Thismeansthateachbookcosts19.50. This means that each book costs 9.75 (19.50 ÷ 2).

Looking at Table B, we can see that this price per book is consistent. For 1 book, the cost is 9.75.For11books,thecostis9.75. For 11 books, the cost is 107.25 (9.75 x 11), and for 121 books, the cost is $1,180.75 (9.75 x 121).

Therefore, Table B correctly represents the relationship between the number of books and the total price.
