You invested $1600 at a 4.18% simple annual interest rate. How long, in years, was your money invested?
~~~~~~~~~~~~~~~~~~~~~~~~~


<pre>
    2150 = 1600*(1 + 0.0418*t)


    {{{2150/1600}}} = 1 + 0.0418t


    1.34375 = 1 + 0.0418*t


    0.34375 = 0.0418t


    t = {{{0.34375/0.0418}}} = 8.224  years.    <U>ANSWER</U>
