document.write( "Let D be the amount invested in desktop computers.\r\n" );
document.write( "\r\n" );
document.write( "Then the amount invested in the notebook computers is (50000-D).\r\n" );

document.write( "The total profit equation is\r\n" );
document.write( "\r\n" );
document.write( "    0.2*D + 0.25*(50000-D) = 0.23*50000.\r\n" );

document.write( "    D =  = 20000.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "ANSWER.  The amount invested at desktop computers is 20000 dollars.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "CHECK.  0.2*20000 + 0.25*(50000 - 20000) = 11500 = 0.23*50000.   ! Correct !\r\n" );
