$95100.00 is invested for 20 years using simple interest. If the future value is $165474.00, what is the intrest rate. Round you answer to the nearest tenth of a percent. $LaTeX: \displaystyle </p>$

Using $LaTeX: \displaystyle FV = PV +PVrt \iff FV - PV = PVrt \iff r = \frac{FV - PV}{PVt}$ . Evaluating gives $LaTeX: \displaystyle r = \frac{165474.0-95100 }{(95100)(20) } = 0.037 = 3.7%$
