\n" );
document.write( "Hi,
\n" );
document.write( "Let x be the water added
\n" );
document.write( ".30*50 = .20(50 L +x)
\n" );
document.write( "simplify and Solve
\n" );
document.write( ".30*50 - .20*50 L = .20x
\n" );
document.write( ".10*50L = .20x
\n" );
document.write( "25L = x
\n" );
document.write( "25 liters of water would need to be added
\n" );
document.write( "checking our answer
\n" );
document.write( "15 = .20(75) \n" );
document.write( "

\n" );
