\r\n" );
document.write( "Let x be the volume of the oil containing 10% saturated fat.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Then you write this equation\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "    0.1x + 0.22*20 = 0.16(x+20).\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "It says that the sum of saturated fats in ingredients is the same as that in the final mixture.\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 = \"%280.16%2A20-0.22%2A20%29%2F%280.1+-+0.16%29\" = 20.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "ANSWER.  20 ounces of the vegetable oil containing 10% of saturated fat should be added.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "CHECK.   I will check for the concentration  \"%280.1%2A20%2B0.22%2A20%29%2F%2820%2B20%29\" = 0.16 = 16%.   ! Correct !\r\n" );
