A company is considering an investment project with the following cash flows: Initial investment at Year 0 of $7,000,000, cash inflows of $3,000,000 in Year 1, $4,000,000 in Year 2, and $2,500,000 in Year 3. The cost of capital is 14%.

1. Calculate the Net Present Value (NPV) of the project.
2. Determine the Internal Rate of Return (IRR) for the project.
3. If the company's required rate of return is 14%, should the project be accepted based on the NPV rule?
4. Calculate the Profitability Index (PI) for the project.
5. Compute the payback period.
