percent ---------------- quantity
\n" ); document.write( "Acid type I 60.00% ---------------- x liters
\n" ); document.write( "acid type II 30.00% ------ 60 - x liters
\n" ); document.write( "Mixture 40.00% ---------------- 60
\n" ); document.write( "Total 60 liters
\n" ); document.write( "60.00% x + 30.00% ( 60 - x ) = 40.00% * 60
\n" ); document.write( "60 x + 30 ( 60 - x ) = 2400
\n" ); document.write( "60 x + 1800 - 30 x = 2400
\n" ); document.write( "60 x - 30 x = 2400 - -1800
\n" ); document.write( "30 x = 600
\n" ); document.write( "/ 30
\n" ); document.write( " x = 20 liters 60.00% Acid type I
\n" ); document.write( " 40 liters 30.00% acid type II
