Poor Dog, Inc. borrowed $135,000 from the bank today. They must repay this money over the next six years by making monthly payments of $2,215.10. What is the interest rate on the loan? Express your answer with annual compounding.

Here is what I put in

n = 72

I% = 0

PV = -135000

PMT = 2215.1

FV = 0

p/y = 12

c/y = 12

and the answer I get is 5.65% which is wrong, the correct answer is 5.80% and I have no idea how to get it.
