\r\n" );
document.write( "Let  x = How many pounds of a chicken feed that is 35% corn must be used.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "0.35x + 0.8*320 = 0.75*(x+320).    (It is the balance equation for corn in the chicken feed)\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "0.35x + 0.8*320 = 0.75x + 0.75*320,\r\n" );
document.write( "\r\n" );
document.write( "0.8*320 - 0.75*320 = 0.75x - 0.35x \r\n" );
document.write( "\r\n" );
document.write( "0.05*320 = 0.4x  ====>  x = \"%280.05%2A320%29%2F0.4\" = 40.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Answer.  40 pounds of a chicken feed that is 35% corn must be used.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Check.  0.35*40 + 0.8*320 = 270 pounds of corn.\r\n" );
document.write( "\r\n" );
document.write( "        0.75*(40+320) = 270 pounds of corn.    ! Correct !\r\n" );
