May someone please help me with this problem? I don't the previous posters had all the answers correct. I also need to receive the Excel file and not just screen shoots as I need to see your formulas. Please help ASAP!

After extensive research and development, Goodweek Tires, Inc., has recently developed a new tire, The research and development costs so far have totaled about $10 million. The SuperTread would be put on the market beginning this year, and Goodweek expects it to stay on the market for a total of four years. Test marketing costing $5 million has shown that there is a significant market for a SuperTread-type tire. Except for the initial investment that will occur immediately, assume all cash flows will occur at year-end. Goodweek must initially invest $160 million in production equipment to make the SuperTread. This equipment can be sold for $65 million at the end of four years. Goodweek intends to sell the SuperTread to two distinct markets: 1. The original equipment manufacturer (OEM) market: The OEM market consists pri-marily of the large automobile companies (like General Motors) that buy tires for new cars. In the OEM market, the SuperTread is expected to sell for $41 per tire. The vari-able cost to produce each tire is $29. 2. The replacement market: The replacement market consists of all tires purchased after the automobile has left the factory. This market allows higher margins; Goodweek expects to sell the SuperTread for $62 per tire there. Variable costs are the same as in the OEM market. Goodweek Tires intends to raise prices at 1 percent above the inflation rate; variable costs will also increase at 1 percent above the inflation rate. In addition, the SuperTread project will incur $43 million in marketing and general administration costs the first year. This cost is expected to increase at the inflation rate in the subsequent years. Goodweeks corporate tax rate is 40 percent. Annual inflation is expected to remain constant at 3.25 percent. The company uses a 13.4 percent discount rate to evaluate new product decisions. Automotive industry analysts expect automobile manufacturers to produce 6.2 million new cars this year and production to grow at 2.5 percent per year thereafter. Each new car needs four tires (the spare tires are undersized and are in a differ-ent category). Goodweek Tires expects the SuperTread to capture 11 percent of the OEM market. Industry analysts estimate that the replacement tire market size will be 32 million tires this year and that it will grow at 2 percent annually. Goodweek expects the SuperTread to capture an 8 percent market share. The appropriate depreciation schedule for the equipment is the seven-year MACRS depreciation schedule. The immediate initial working capital requirement is $9 million. Thereafter, the net working capital requirements will be 15 percent of sales. What are the NPV, payback period, discounted payback period, IRR, and PI on this project?
