I need to see the steps/ explanation to computations, like formulas, so I can really understand how to do this.

A company just paid $10 million for a feasibility study. If the company goes ahead with the project, it must immediately spend another $123,813,463 now, and then spend $20 million in one year. In two years it will receive $80 million, and in three years it will receive $90 million. If the cost of capital for the project is 11 percent, what is the projects NPV?
