3. The relationship between marginal and average costs
Consider the following scenario to understand the relationship between marginal and average values. Suppose Eleanor is a professional basketball
player, and her game log for free throws can be summarized in the following table.
Fill in the columns with Eleanor's free-throw percentage for each game and her overall free-throw average after each game.

On the following graph, use the orange points (square symbol) to plot Eleanor's free-throw percentage for each game individually, and use the green
points (triangle symbol) to plot her overall average free-throw percentage after each game.
Note: Plot your points in the order in which you would like them connected. Line segments will connect the points automatically.

GAME
You can think of the result in any one game as being Eleanor's marginal free-throw percentage. Based on your previous answer, you can deduce that
when Eleanor's marginal free-throw percentage is above the average, the average must be
You can now apply this analysis to production costs. For a U-shaped average total cost (ATC) curve, when the marginal cost curve is below the
average total cost curve, the average total cost must be
Also, when the marginal cost curve is above the average total cost curve,
the
average total cost must be
Therefore, the marginal cost curve intersects the average total cost curve
