How do we calculate each of the following: marginal cost, average total cost, and average variable cost?

Average cost curves (except for avenge fixed cost) tend to be U-shaped, decreasing and then increasing. Marginal cost curves have the same shape, though this may be harder to see since most of the marginal cost curve is increasing. Why do you think that average and marginal cost curves have the same general shape?

Return to Figure 7.7. What is the marginal gain in output from increasing the number of batters from 4 to 5 and from 5 to 6? Does it continue the pattern of diminishing marginal returns? Figure 7.7 How output Affects Total costs

What is die difference between accounting and economic profit?

A common name for fixed cost is overhead. If you divide fixed cost by the quantity of output produced, you get average fixed cost. Supposed fixed cost is 1,000. What does the average fixed cost curve look like? Use your response to explain what spreading the overhead means.

What is a production function?
