If the initial investment was for $110,000 but each year the stream of cash flows and investment holding period changed to the following:

Year 1: $13,100

Year 2: $17,800

Year 3: $22,400

Year 4: $20,100

Year 5: $23,000

Year 6: $23,900

Year 7: $28,900

What would be the NPV at a 5%, 10%, 15%, and 20% discount rate? What is the IRR of the above investment?
