The following table shows the cost information for a product at the 15,000-units level. Use the table to answer these questions: What are the incremental and marginal costs for producing 5,000 additional units? Suppose that, at a new production level of 30,000, the fixed cost increases to $3 million, what are the incremental and marginal costs for the additional 10,000 units? All cost figures are in dollars. Calculate [USING EXCEL]
