Question 163628
</pre><font size=4><b>
{{{x}}}= amount invt. @4%
{{{33000-x}}}= amount invt. @2.25%
Therefore,
{{{0.04x+0.0225(33000-x)=970}}}, eqn 1
{{{0.04x+742.50-0.0225x=970}}}
{{{0.0175x=970-742.50=227.50}}}
{{{cross(0.0175)x/cross(0.0175)=cross(227.50)13000/cross(0.0175)}}}
{{{x=13000}}} --------------> amount invt. @4%
{{{33000-13000=20000}}} -----------> amount invt. @2.25%
Check via eqn 1,
{{{0.04(13000)+0.0225(20000)=970}}}
{{{520+450=970}}}
{{{970=970}}}
Thank you,
