To determine the cost of the books, we need to analyze the graph. The horizontal axis represents the number of books, and the vertical axis represents the cost in dollars.
Based on the information given, the total purchase was $31.50. To find the cost of the books, we need to find the point on the graph that corresponds to $31.50 on the vertical axis.
Looking at the graph, we can see that the point where the vertical axis intersects $31.50 is at the point where the horizontal axis is at around 4 on the scale. This means that the cost of purchasing 4 books is $31.50.
Therefore, the cost of the books is approximately $31.50 - the shipping fee.
Since the shipping fee is a flat fee for each order and there was no sales tax, we can conclude that the books alone cost $31.50 - the flat shipping fee.
Given the options provided, the closest answer would be:
D. $31.50
Please note that this is an estimation based on the given information and the graph. The actual cost might vary depending on the precise values and accuracy of the graph.
