Explain why the marginal cost curve intersects a U-shaped average cost curve at its minimum point. What will be an ideal response? ANSWER At low quantities, the average cost curve declines as the quantity increases. The marginal cost is below the average cost. The marginal cost represents the cost of an additional unit of […]
