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 = $5.5b+7.5$

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.
