I need the answer to the last question and the calculation process.

You are considering a new product launch. The project will cost $2,100,000, have a 4-year life, and have no salvage value; depreciation is straight-line to 0. Sales are projected at 160 units per year; price per unit will be $27,000; variable cost per unit will be $16,500; and fixed costs will be $570,000 per year. The required return on the project is 14%, and the relevant tax rate is 32%. a. Based on your experience, you think the unit sales, variable cost, and fixed cost projections given here are probably accurate to within +10%. 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? (Negative answers should be indicated by a minus sign. Do not round intermediate calculations. Round the final NPV answers to 2 decimal places. Omit $ sign in your response.) Scenario Base Best Worst Unit Sales 160 176 Variable Cost $ 16500 $ 14850 $ 18150) Fixed Costs $ 570000 $ 513000 $ 627000 NPV $ 588773.7 $ 1609948. $ -327786. 144 b. Evaluate the sensitivity of your base-case NPV to changes in fixed costs. (Negative answers should be indicated by a minus sign. Do not round intermediate calculations. Round the final answer to 3 decimal places. Omit $ sign in your response.) ANPV/AFC $ -1.98 c. What is the cash break-even level of output for this project (ignoring taxes)? (Round the final answers to the nearest whole unit.) Cash break-even 54.29 units d-1. What is the accounting break-even level of output for this project? (Round the final answers to the nearest whole unit.) Accounting break-even 104.29 units d-2. What is the degree of operating leverage at the accounting break-even point? (Round the final answer to 4 decimal places.) Degree of operating leverage
