GreenTech is considering investing in a new renewable energy project. The project involves setting up a

wind turbine farm, which requires an initial investment of $$115$ million. Financial analysts estimate that

the benefits of the new project will be $$20$ million per year, starting at the end of the first year and

lasting for eight years. After eight years, the benefits are expected to start declining by $2\%$ per year

indefinitely $($Year $9$ is the last year you the project yields $$20$ million$).$ Assume the discount rate is $14\%.$

Please calculate the following:

$6.$ Net Present Value $($NPV$),$ in millions $7.$Internal Rate of Return $($IRR$)8.$ Payback Period, in years. Help on all three if possible please
