What is the present value of the following

planned cash flow for a $30$ year power plant project?

Assume that the annual cost of money is $3\mathrm{.}9\%.$ Draw

the cash flow diagram and present your solution.

Initial Investment $($construction costs$)-$ $$75,000,000$

Annual operating costs $-$ $$1,000,000$

Annual maintenance costs $-$ $$95,000$

Projected decommissioning expenses $$ $$20,000,000$

Projected income from scrap $-$ $$250,000$

Please use the simple PV $($non abbreviated$)$ formulas and a simple non excel cash flow so that is it easier to understand. Thank you.
