Deriving the Slope of the Average Cost Curve
The slope of the average cost (AC) curve can be mathematically determined by taking the derivative of the average cost function with respect to the quantity of output (Q). Since the average cost is defined as the total cost divided by quantity (), finding its slope requires applying the quotient rule of differentiation.

A company is producing 500 units of a product. At this output level, the cost of producing the 501st unit is $12, while the average cost for each of the 500 units is $18. Based on this information, which course of action should the company take if its goal is to lower its average cost per unit, and why?

A firm's total cost (TC) of production for different quantities (Q) is shown in the table below.
Quantity (Q) Total Cost (TC) 10 $200 11 $209 12 $222 Based on this data, how does the firm's average cost change when production increases from 11 to 12 units, and why?
A business consultant analyzes a company's production data and makes the following statement: 'At your current output of 1,000 units, your average cost per unit is $50, which is the lowest possible average cost for your firm. My analysis also shows that the cost to produce the 1,001st unit would be $45.' Based on the principles relating the cost of an additional unit to the average cost, is the consultant's statement logically sound?

Calculating the Slope of the Average Cost Curve
Analyzing the Slope of an Average Cost Curve
A firm's average cost (AC) is defined as its total cost function, C(Q), divided by the quantity of output, Q. To find the slope of the average cost curve, one must differentiate the AC function, , with respect to Q. Arrange the following mathematical operations in the correct sequence as dictated by the rule for differentiating a quotient.
If a firm's total cost function is represented by C(Q), the slope of its average cost curve is correctly calculated by finding the marginal cost, C'(Q), and then dividing that result by the quantity of output, Q.
A firm's average cost (AC) is defined as total cost, C(Q), divided by output, Q. The slope of the AC curve is found by differentiating the function with respect to Q. Match each mathematical term from this calculation to its correct economic or mathematical description.
