I want step by step answer with formula

A private school is considering the purchase of six school buses to transport students to and from school events. The initial cost of the buses is $600,000. The life of each bus is estimated to be five years, after which time the vehicles would have to be scrapped with no salvage value. The school? s management team has derived the following estimates for annual revenues and cost for the next five years. Year Years. 1. 2. 3. 4. 5. Revenues. 330,000. 330,000.350,000. 380,000. 400,000 Drivers Cost 33,000.35,000.36,000. 38,000.40,000 Other Costs. 130,000. 135,000.140,000. 136,000. 142,000 Repairs & Mai 8,000. 13,000. 15,000. 16,000. 18,000 Depreciation. 120,000. 120,000. 120,000. 120,000. 120,000 The buses would be purchased at the beginning of the project (i.e., in Year O) and all revenues and expenditures shown in the table above would be incurred at the end of each relevant year. Because schools are exempt from taxes, the school?s corporate tax rate is 0 percent. A business consultant has advised management that they should use a weighted average cost of capital (WACC) of 10.5 percent to evaluate this project. I. Prepare a table showing the estimated net cash flows for each year of the project. Explain all steps involved in your calculation of the Year 1 estimated net cash flow. II. Calculate the project?s Payback Period. Explain in your own words, all steps involved in the calculation process. III. Calculate the project?s Internal Rate of Return (IRR). Explain in your own words, all steps involved in the calculation process. IV. Calculate the project?s Net Present Value (NPV). Explain in your own words, all steps involved in the calculation process. V. Which is the three evaluation techniques that you computed (i.e., payback period, IRR and NPV), should the firm use to make its decision of whether or not to accept this project? Why? Is one of these techniques better than the others and if so, why
