\r\n" );
document.write( "Let x be the amount of the 15% solution, in milliliters.\r\n" );
document.write( "\r\n" );
document.write( "Then the amount of the 20% solution is 50-x milliliters.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "The equation to find \"x\" is this\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "    0.15x + 0.20*(50-x) = 0.18*50.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "It says that the amount of the pure acid HCl in the mixture is the sum of the amounts of the pure acid HCl in the ingredients.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Express x from the equation and calculate\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "    x = \"%280.18%2A50+-+0.20%2A50%29%2F%280.15-0.20%29\" = 20 milliliters.    ANSWER\r\n" );
