\n" ); document.write( "An executive invests $21,000, some at 8% and the rest at 6% Annual interest. if he receive an annual return of &1,620, how much is invested at each rate
\n" ); document.write( "At 8% interest =
\n" ); document.write( "At 6% interest =
\n" ); document.write( "

Let amount invested at 8% be E
\n" );
document.write( "Then amount invested at 6% = 21,000 - E
\n" );
document.write( "We then get: .08E + .06(21,000 - E) = 1,620
\n" );
document.write( ".08E + 1,260 - .06E = 1,620
\n" );
document.write( ".08E - .06E = 1,620 - 1,260
\n" );
document.write( ".02E = 360
\n" );
document.write( "Amount invested in the 8%-fund, or 
\n" );
document.write( "You should now be able to find the amount invested in the 6% fund. \n" );
document.write( "

\n" );
