interest = principal x rate x time
interest = 1344-1200 = 144
principal = 1200
rate = 8% = .08
144 = 1200 x .08 x Time
Time = 1.5 yrs
Well, from 2008 to 2010 is just 2 years, so let's say the initial amount is the 19300 from 2008, how many will it be in 2010?
5578/68=82.029411764705882352941176470588
that would be rounded to 82.02 which is the answer
