Kelsey had $65 to spend on books. Each book cost $5.50, and there was a $7.50 fee for shipping. She let b equal the number of bo
GuDViN [60]

Answer:

Let the number of books she can purchase = b

The cost of each book is $5.5 with an extra shipping of $7.5

So, the total cost of the books she can purchase = 5.5b+7.5

Since, she had $65 to spend on the books.

The required inequality is 5.5b+7.5\leq 65.

So, according to the inequality above, we get,

The correct options are,

B. The inequality symbol is incorrect because she can spend up to and including $65.

C. The expression  5.5b+7.5 is correct because $5.50 per book is  5.5b and that is added to the shipping fee of $7.50 to determine the total purchase price.
