\r\n" );
document.write( "Let x = the volume of the 10% solution.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Then the basic equation is\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "    0.1*x + 0.25*1 = 0.15(x+1)\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "saying that total volume of the pure acid in the mixture is the sum of the volumes of the pure acid in ingredients.\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 =  = 2.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "ANSWER.  2 liters of the 10% acid solution.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "CHECK.   0.1*2 + 0.25*1 = 0.45 = 0.15*(2 + 1) = 0.15*3.   ! Correct !\r\n" );
