Hello I need help doing questions 2-4 in excel with formulas please

You are considering a new product launch. The project will cost $5,000,000, have a five-year life, and have no salvage value; depreciation is straight-line to zero. Sales are projected at 750 units per year; price per unit will be $15,500, variable cost per unit will be $12,000, and fixed costs will be $850,000 per year. The required return on the project is 12 percent, and the relevant tax rate is 30 percent. Based on your experience, you think the unit sales are accurate only to within 12%, variable costs are accurate only to within 10%, and fixed cost projections given here are probably accurate to within 8 percent. (You don't need to consider the NWC for this question. (25 Points) Questions: 1. What are NPVs for the base-case, the best-case and worst-case scenarios? 2. What is the accounting break-even level of output for this project (ignoring taxes)? 3. What is the cash break-even level of output for this project (ignoring taxes)? 4. What is the financial break-even level of output for this project (ignoring taxes)
