Explanation
Some values below may show as rounded for display purposes, though unrounded numbers should be used for actual calculations.

FV = PV × (1 + r)t
r = (FV / PV)1/t – 1
     
r = ($825 / $410)1/12 – 1 = 0.0600, or 6.00%
r = ($289 / $188)1/5 – 1 = 0.0898, or 8.98%
r = ($310 / $310)1/8 – 1 = 0.0000, or 0%
