Percent ---------------- quantity
\n" ); document.write( "Solution I 20.00% ---------------- x pints
\n" ); document.write( "Solution II 50.00% ------ 8 - x pints
\n" ); document.write( "Mixture 30.00% ---------------- 8
\n" ); document.write( " 8
\n" ); document.write( "20.00% x + 50.00% ( 8 - x ) = 30.00% * 8
\n" ); document.write( "20 x + 50 ( 8 - x ) = 240
\n" ); document.write( "20 x + 400 - 50 x = 240
\n" ); document.write( "20 x - 50 x = 240 - -400
\n" ); document.write( "-30 x = -160
\n" ); document.write( "/ -30
\n" ); document.write( " x = 5.33 pints 20.00% Solution I
\n" ); document.write( " 2.67 pints 50.00% Solution II
