A two year project requires a $$100,000$ initial investment. In the following two year it will generate positive cash flow: $$70,000$ in the first year and $$50,000$ and in the second $.$

a$.$ Calculate the project Net Present Value if the discount rate is $13\%?$ Try $14\%?$

b$.$ From the results in a$,$ can you guess a possible range for IRR?

c$.$ What is the project IRR $($you can use excel for this, however, if you consider: $x=\frac{1}{1+\text{I}\text{R}\text{R}},$ you can write the problem as a quadratic function and solve manually$)$

Solve in excel please!!!
