Hello, I am having trouble with this question. I am using the HP 10bii+ calculator. A step by step instructions on using the calculator, not excel, will help me the most. I know the answer, just not how to enter it into the calculator to get the correct answer, i keep getting it wrong. Thank you!

What is the IRR of the following set of cash flows? (Do not round intermediate calculations. Enter your answer as a percent rounded to 2 decimal places, e.g., 32.16.)

Year	Cash Flow
0	$	16,600
1		7,300
2		8,600
3		7,100

Once again, I know the answer just not how to get it using the HP 10bII+ financial calculator. Thank you for your help.
