Question 877008: I'm trying to determine the return interest rate of a whole life policy over the course of 20 years. The monthly payment is $169 and the total comes out to $52,000.

The number that I get when putting my equation into the Universal Simplifier and equation solver program linked above is 1.28 but that does not seem right to me at all. Can you please help me? Thank you for your assistance!
