Cash Flow
Number
Cash Flow Amount Occurrences
1 5,000.00 1
2 4,500.00 1
3 0.00 1
4 4,000.00 1
5 5,000.00 5
6 115,000.00 1
Given this information, calculate the total of the cash flows and the internal rate of return (IRR) of the investment.
Calculate net present value (NPV) and net future value (NFV), assuming an annual investment interest rate of 10.5%. See
