Understanding Cost Curves in Economics

What is the definition of average cost (AC)?

• The cost of producing one additional unit of output.

• The total cost divided by the number of units produced.

• The difference between total revenue and total cost.

• The cost of raw materials used in production.

What is the definition of marginal cost (MC)?

• The cost of producing one additional unit of output.

• The total cost divided by the number of units produced.

• The difference between total revenue and total cost.

• The cost of raw materials used in production.

• $20

• $50

• $70

• $100

How does an increase in marginal cost (MC) affect average cost (AC) when production is increased?

• AC decreases.

• AC remains constant.

• AC increases.

• AC becomes zero.

Which of the following best describes the relationship between AC and MC when MC is less than AC?

• AC is increasing.

• AC is decreasing.

• AC is constant.

• AC is zero.

In the context of cost curves, what happens to the AC curve when the MC curve is below it?

• The AC curve rises.

• The AC curve falls.

• The AC curve remains unchanged.

• The AC curve becomes vertical.

Which of the following is a real-life application of understanding the relationship between AC and MC?

• It helps firms manage production costs effectively.

• It determines the selling price of a product.

• It calculates the total revenue of a firm.

• It predicts consumer demand.

Why is it important for a firm to understand the relationship between average cost and marginal cost?

• To increase the number of employees.

• To optimize its production strategy.

• To reduce the quality of products.

• To increase the selling price of products.
