\r\n" );
document.write( "\r\n" );
document.write( "Let x = how much was invested at 8%.\r\n" );
document.write( "\r\n" );
document.write( "Then 40000-x was invested at 2%.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "The total interest equation is\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "    0.08x + 0.02(40000-x) = 1760  dollars.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "From the equation\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "    x = \"%281760-0.02%2A40000%29%2F%280.08-0.02%29\" = 16000.      \r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "ANSWER.  $16000 invested at 8% and the rest, 40000-16000 = 24000  dollars invested at 2%.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "CHECK.   0.08*16000 + 0.02*24000 = 1760  dollars, total annual interest.     ! Precisely correct !\r\n" );
