need help on the math!

You are a Vice President at the investment bank Goldman Sachs. You just had a meeting with Roger Moore, CEO of Moore Metals, which is considering the purchase of Viking Platinum Mine in Greenland. The Viking Platinum Mine has seven years of ore remaining. The following is a pro-forma schedule of incremental cash flows from the mine. Schedule of Incremental Cash Flows Year Amount 0 $(295,000,000) 1 33,000,000 2 65,000,000 3 98,000,000 4 120,000,000 5 100,000,000 6 80,000,000 7 95,000,000 The current owners of the mine are asking $295,000,000 cash, payable at closing. Roger thinks that the proper way to make this ital budgeting decision is via the payback method, with a five-year time frame, but he is not sure. Roger has come to you for advice. You agree that Goldman Sachs will evaluate the project for a fee of $250,000. ASSIGNMENT: Write a DOUBLE-SPACED letter to Roger which: 1. Starts with an introductory statement of purpose 2. Addresses why the payback method is not the appropriate way to evaluate whether to undertake this project 3. Describes the net present value method and its advantages 4. Presents the net present value of the deal, assuming that Moore Metals' required return, or discount rate, is 15%. 5. Recommends whether or not to do the deal for $295,000,000 cash at closing
