\r\n" );
document.write( "OK, let us measure the volume in cups. Why not?\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Let \"n\" be the number of cups of the 10% solution.\r\n" );
document.write( "\r\n" );
document.write( "Then the number of the 20% solution is 5-n.\r\n" );
document.write( "\r\n" );

document.write( "\r\n" );
document.write( "0.1n + 0.2*5 - 0.2n = 5*0.12,\r\n" );

document.write( "Answer.  4 cups of the 10% solution must be mixed with 5-4 = 1 cup of the 20% solution.\r\n" );
