Question 160297
</pre.<font size=4><b>
Let "x", amount invested at 9%. So "24000-x" is the amount inv. at 6%.
Putting into eqn:
{{{0.09x+0.06(24000-x)=1740}}} working eqn
{{{0.09x+1440-0.06x=1740}}}
{{{0.03x=1740-1440}}}
{{{0.03x=300}}}
{{{cross(0.03)x/cross(0.03)=cross(300)10000/cross(0.03)}}}
{{{x=10000}}} --------------> amt invested at 9%
{{{24000-10000=14000}}}-----> amt invested at 6%
check via working eqn:
{{{0.09*10000+0.06*14000=1740}}}
{{{900+840=1740}}}
{{{1740=1740}}}
Thank you,
