$86840.00 dollars is invested at 4.4% using simple interest. If the future value is $136512.48, how long was it invested? Round to the nearest tenth of a year.
Using \(\displaystyle FV = PV +PVrt \iff FV - PV = PVrt \iff t = \frac{FV - PV}{PVr}\). Evaluating gives \(\displaystyle t = \frac{136512.48-86840}{(86840)(0.044)} = 13.0\) years
