$65050.00 dollars is invested at 4.6% using simple interest. If the future value is $112926.80, 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 \(\displaystyle t = \frac{112926.8-65050}{(65050)(0.046)} = 16.0\) years
