Question 1157482
<br>
$600 interest means the original $1200 has grown to $1800.<br>
If t is the number of years and the interest is 5% compounded quarterly, then<br>
{{{1800 = 1200(1+.05/4)^(4t)}}}<br>
Graph using a graphing calculator, or solve using logarithms....<br>
{{{1.5 = 1.0125^(4t)}}
{{{log((1.5)) = 4t*log((1.0125))}}}
{{{4t = log((1.5))/log((1.0125))}}}<br>
You can finish....<br>
