\r\n" );
document.write( "Let x be \"How much pure apple juice should she use\", in liters.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Then the volume of the 40% juice to mix is (2-x) liters.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Then your concentration equation is\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "     = 0.8,\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "saying that the ratio of the pure apple juice to the total volume of 2 liters is 0.8 = 80%.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Solve it step by step:\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "    0.4*(2-x) + x = 0.8*2\r\n" );
document.write( "\r\n" );
document.write( "    0.8 - 0.4x + x = 1.6\r\n" );
document.write( "\r\n" );
document.write( "    0.6x = 1.6 - 0.8\r\n" );
document.write( "\r\n" );
document.write( "    0.6x = 0.8  ====>  x =  =  =  =  liters   ANSWER\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Check.    = 0.8.    ! Exactly correct !\r\n" );
