Marginal cost cuts the average variable cost curve at AVC’s:
A. Maximum point.
B. Starting point on the vertical axis.
C. Intersection with the demand curve.
D. Minimum point.✓ 答案
解說
When MC is below AVC, producing one more unit pulls the average down. When MC is above AVC, it pulls the average up. So MC crosses AVC at the bottom of the U. This is a cost-curve fact, not a demand intersection.
