\n" ); document.write( "
\r\n" );
document.write( "10 liters of the 15% alcohol drink contain 0.15*10 liters of pure alcohol.\r\n" );
document.write( "\r\n" );
document.write( "If you add  W liters of water, the mixture will contain the same 0.15*10 liters of alcohol, but the total liquid volume will be (10+W) liters.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "You need to find W under the condition\r\n" );
document.write( "\r\n" );
document.write( "\"%280.15%2A10%29%2F%2810%2BW%29\" = 0.05,\r\n" );
document.write( "\r\n" );
document.write( "which is the condition that the mixture is 5% alcohol.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "OK. You just have an equation.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "To solve it, multiply both sides by (10+W). You will get\r\n" );
document.write( "\r\n" );
document.write( "0.15*10 = 0.05*(10+W),\r\n" );
document.write( "\r\n" );
document.write( "1.5 = 0.5 + 0.05W  ====>  0.05W = 1.5 - 0.5 = 1  ====>  W = \"1%2F0.05\" = 20.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Answer.  20 liters of water must be added.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Check.  \"%281.5%2A10%29%2F%2810%2B20%29\" = \"1.5%2F30\" = 0.05 = 5%.\r\n" );
