-------------- percent ---------------- Amount
\n" ); document.write( "alcohol type I 15 ---------------- 225 ml
\n" ); document.write( "alcohol type II 95 ---------------- x ml
\n" ); document.write( "Mixture 80 ---------------- 225 + x ml
\n" ); document.write( "
\n" ); document.write( "15 * 225 + 95 x = 80 ( 225 + x )
\n" ); document.write( "3375 + 95 x = 18000 + 80 x
\n" ); document.write( "95 x -80 x = -3375 + 18000
\n" ); document.write( "15 x = 14625
\n" ); document.write( "/ 15
\n" ); document.write( "x = 975 ml alcohol type II
