Short-Run Production Costs - AP Microeconomics

ATC decreases. Lower variable costs reduce average total cost.

$TVC = $250. Using the relationship $TVC = TC - TFC$.

$ATC = $15. Using the relationship $ATC = AFC + AVC$.

$TC = $500. Using the formula $TC = TFC + TVC$.

$TVC = $200. Using the formula $TVC = AVC \times Q$.

$AVC = \frac{TVC}{Q}$. Variable costs per unit of output.

$AFC = \frac{TFC}{Q}$. Fixed costs spread over quantity produced.

$MC = 10$. Using the formula $MC = \frac{\triangle TC}{\triangle Q}$.

ATC = $12$. Using the formula $ATC = \frac{TC}{Q}$.

$ATC = 10$. Using the formula $ATC = \frac{TC}{Q}$.

$MC = \frac{\triangle TC}{\triangle Q}$. Change in total cost per additional unit produced.

Average Total Cost (ATC) curve. Falls initially due to fixed cost spreading, then rises.

Typically U-shaped. Reflects diminishing marginal returns in production.

MC is less than ATC. When marginal cost is below average, it pulls average down.

At the minimum point of ATC. MC intersects ATC at its lowest point.

ATC increases. When marginal exceeds average, it pulls average up.

AVC is decreasing. When marginal is below average, it pulls average down.

Initially decreases, then increases. U-shaped due to efficiency gains then diminishing returns.

$MC = $10. Using the formula $MC = \frac{\triangle TC}{\triangle Q}$.

$AFC = \frac{TFC}{Q}$. AFC equals fixed costs divided by output.

$AFC = $8. Using the formula $AFC = \frac{TFC}{Q}$.

TVC is zero. No production means no variable expenses.

MC equals AVC. MC intersects AVC at its lowest point.

$TVC = $250. Using the relationship $TVC = TC - TFC$.

$AVC = $12. Using the formula $AVC = \frac{TVC}{Q}$.

MC equals ATC. At the minimum, marginal equals average.

ATC increases. Higher fixed costs increase average total cost.

AVC is at its minimum. At minimum AVC, marginal cost equals average variable cost.

MC is greater than ATC. When marginal exceeds average, average increases.
