Company is planning to invest in a new development. The cost of the project will be $23 million and is expected to generate cash flows of $14,000,000, $11,750,000, and $6,350,000 over the next three years. The company's cost of capital is 20 percent. What is the internal rate of return on this project? (Round to the nearest percent.)

I need to see the equation with the numbers in it so I understand how to do the calculation.
