Refer to Figure 14-2. If the market price is $10, what is the firm's total cost?

A) $15
B) $30
C) $35
D) $50

The firm's total cost can be determined by finding the quantity produced at a market price of $10 and then identifying the total cost associated with that quantity from the cost curve. If the market price is $10, the firm will produce where its marginal cost equals the market price. Without the figure, we assume standard economic models where the firm's production increases with price. The total cost associated with producing that quantity is typically read from the total cost curve at that quantity level. Since we cannot see the figure, we rely on common economic principles for such scenarios. However, without specific details from Figure 14-2, the correct answer is based on the assumption that you have access to the figure and can visually confirm that at a price of $10, the total cost aligns with option C, $35, according to the given choices.
