\r\n" );
document.write( "Let W be the volume of water to add, in milliliters.\r\n" );
document.write( "\r\n" );
document.write( "Then the volume of the new solution is 250+W milliliters.\r\n" );
document.write( "\r\n" );
document.write( "The salt contents is and will be the same: 0.3*250 grams.\r\n" );
document.write( "\r\n" );
document.write( "Related to 250+W milliliters of solution, the new concentration is\r\n" );
document.write( "\r\n" );
document.write( ".\r\n" );
document.write( "\r\n" );
document.write( "It should be 20% concentration, which gives you an equation\r\n" );
document.write( "\r\n" );
document.write( " = 0.2,   or\r\n" );
document.write( "\r\n" );
document.write( "0.3*250 = 0.2*(250+W),\r\n" );
document.write( "\r\n" );
document.write( "75 = 50 + 0.2W  --->  0.2W = 75-50 = 25  --->  W =  = 125.\r\n" );

document.write( "\r\n" );
document.write( "Answer. 125 milliliters of water must be added.\r\n" );
