Statement 1: we've got 40 books, but we have no idea how much each book costs. Not sufficient.
Statement 2: Nothing about the number of books. Not sufficient.
Together: We know there are 40 books, but the cost per book could be exactly $12.50, or it could be $14 or $15, etc. Because we don't know the cost per book, the statements together are not sufficient to answer the question. The answer is E
