\n" );
document.write( "How many liters of pure baking soda must be added to get a 60% baking soda solution
\n" );
document.write( "Let x be the number of liters of pure baking soda to be added
\n" );
document.write( ".30*100L  + 1.00*x = .60(100L + x)
\n" );
document.write( ".30*100L  + 1.00*x = .60*100L + .60x
\n" );
document.write( "simplify and solve
\n" );
document.write( "x - .60x = .60*100L  - .30*100L
\n" );
document.write( ".4x = .30*100L
\n" );
document.write( "x = 75L
\n" );
document.write( "checking our answer
\n" );
document.write( "30L + 75L = .60*175L = 105L \n" );
