If I invest $25,000 in two different stocks. One earns 6.5% and the other earns 7.00%. If the total interest earnings for one year is 1683.75, how much is invested in each stock?
\n" ); document.write( "------------
\n" ); document.write( "Let amount invested at 6.5% be \"x\".
\n" ); document.write( "Interest on this money is 0.065x dollars.
\n" ); document.write( "--------
\n" ); document.write( "Amount invested at 7% is \"25000-x\"
\n" ); document.write( "INterest on this money is 0.07(25000-x)=1750-0.07x dollars
\n" ); document.write( "-------------
\n" ); document.write( "EQUATION:
\n" ); document.write( "interest + interest = 1683.75
\n" ); document.write( "0.065x + 1750-0.07x = 1683.75
\n" ); document.write( "-0.005x=-66.25
\n" ); document.write( "x=$13,250 (amount invested at 6.5%)
\n" ); document.write( "25000-x=$38,250 (amount invested at 7%)
\n" ); document.write( "Cheers,
