4.Korea Nuclear Tritium Removal Facility (TRF) project requires an immediate investment of $33 million with a residual value of $7 million at the end of the project. It is expected to yield a net return of $1 million in Year 1 from the sale of immobilized tritium, $5 million dollars in Year 2, $8 million per year for the following six years, and $7 million per year for the remaining four years. Find the internal rate of return of this project. Assume cost of capital for TRF is 10%.

Please help me to solve this problem. Thanks
