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

Charra [1.4K]

Answer:

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

The expression 5. 50b + 7. 5 is correct because $5. 50 per book is 5. 50b and that is added to the shipping fee of $7. 50 to determine the total purchase price.

Explanation:

The inequality should be 5.50b + 7.5 ≤ 65 because she can use less than $65 or all $65 to spend on books.

Also, the shipping fee is for all the books she buys combined, not for each individual book so the left side of the inequality should read 5.50b + 7.5.
