You have a sum on money in an account, and it grows from $ 1,230 to $ 2,244 over a period of 5 years. What average annual rate (%) will produce this result? I know how to use the rate formula in excel but I am confused about which of the values equate to the "Nper", "Pmt", "Pv", "Fv" and the "type". If someone could explain which is the nper versus the pmt etc.. I would appreciate it thanks
