document.write( "Let x be the volume of the 40% juice, in gallons.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Then the amount of the 10% juice is (3-x) gallons.\r\n" );
document.write( "\r\n" );

document.write( "Your equation is\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "    0.4x + 0.1(3-x) = 0.3*3\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "saying that the amount of the pure juice in ingredients is the same as it is in the micture.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "From the equation, express  x  and calculate\r\n" );

document.write( "    x = \"%280.3%2A3+-+0.1%2A3%29%2F%280.4-0.1%29\" = 2.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "ANSWER.  2 gallons of the 40% guice and the rest (3-2) = 1 gallon of the 10% juice.\r\n" );

document.write( ".  \"%282%2A0.4+%2B+1%2A0.1%29%2F%282%2B1%29\" = \"0.9%2F3\" = 0.3 = 30% concentration.  ! Correct !\r\n" );
