To determine the answer, let's analyze the given information. We know that the total purchase cost was $31.50. Now, we need to find the cost of the books itself, excluding the shipping fee.

Looking at the provided graph, we can see that the x-axis represents the number of books, and the y-axis represents the cost. Since we are trying to find the cost of the books, we need to focus on the y-axis.

From the options provided, we can eliminate option D ($31.50) because that is the total purchase cost, not just the cost of the books.

Now, we need to find a point on the graph that corresponds to a cost of $31.50. If such a point exists, it would mean that we are purchasing zero books, which doesn't make sense. Therefore, we can also eliminate option A ($3.50) since it represents the cost of zero books.

Now, we are left with options B ($7.00) and C ($28.00). We need to find which one corresponds to the cost of the books when the total purchase is $31.50.

Since we know that there is a flat fee for shipping on each order, we can deduce that the remaining amount after accounting for the cost of the books should be the shipping fee.

To find the cost of the books, we subtract the shipping fee from the total purchase cost: $31.50 - Shipping Fee.

Option B ($7.00) seems more reasonable for a shipping fee than option C ($28.00). Let's check our calculations:

$31.50 - $7.00 = $24.50 (cost of the books)

Therefore, the correct answer is option B ($7.00).
