\r\n" );
document.write( "Let x be an amount invested at 4%, in dollars.\r\n" );
document.write( "\r\n" );
document.write( "Then the amount invested at 6% is the rest (5500-x) dollars.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Your basic equation is THIS:\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "    interest + interest      = total interest,    or\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "    0.04*x   + 0.06*(5500-x) = 295.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "    0.04x + 0.06*5500 - 0.06x = 295\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "    -0.02x = 295 - 0.06*5500 = -35  ====>  x =  = 1750.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Answer.  $1750 was invested at 4%  and the rest  5500 - 1750 = 3750 dollars was invested at 6%.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Check.   0.04*1750 + 0.06*3750 =  295 dollars.   ! Correct !\r\n" );
