The answers are given. I got the numerical answers wrong, hence the red tab in the top right corners. Those values are correct but I'd like to know how to get those answers. The numbers will change when I attempt the question again.

An integrated, combined cycle power plant produces 295 MW of electricity by gasifying coal. The capital investment for the plant is $570 million, spread evenly over two years. The operating life of the plant is expected to be 20 years. Additionally, the plant will operate at full capacity 77% of the time (downtime is 23% of any given year). The MARR is 9% per year. a. If this plant will make a profit of two cents per kilowatt-hour of electricity sold to the power grid, what is the simple payback period of the plant? Is it a low-risk venture? b. What is the IRR for the plant? Is it profitable? a. The simple payback period of the plant is 14.4 years. (Round up to one decimal place.) It's a high-risk venture. b. The IRR for the plant is 3.6 %. (Round to one decimal place.) The plant is not profitable
