a. Based on your experience, you think the unit sales, variable cost, and fixed cost projections given here are probably accurate to within +10 percent. What are the upper and lower bounds for these projections? What is the base-case NPV? What are the best-case and worst-case scenarios? Note: A negative answer should be indicated by a minus sign. Do not round intermediate calculations. Round your NPV answers to 2 decimal places, e.g., 32.16. Round your other answers to the nearest whole number, e.g. 32.

Note: A negative answer should be indicated by a minus sign. Do not round intermediate calculations and round your answer to 2 decimal places, e.g., 32.16. c. What is the cash break-even level of output for this project (ignoring taxes)? Note: Do not round intermediate calculations and round your answer to 2 decimal places, e.g., 32.16. d-1. What is the accounting break-even level of output for this project? Note: Do not round intermediate calculations and round your answer to 2 decimal places, e.g., 32.16. d-2. What is the degree of operating leverage at the accounting break-even point? Note: Do not round intermediate calculations and round your answer to 3 decimal places, e.g., 32.161. b. ANPV/AFC | c.
