Percent ---------------- quantity
\n" ); document.write( "Solution A 25.00% ---------------- x ounces
\n" ); document.write( "SolutionB 50.00% ------ 120 - x ounces
\n" ); document.write( "Mixture 35.00% ---------------- 120
\n" ); document.write( "Total 120 ounces
\n" ); document.write( "25.00% x + 50.00% ( 120 - x ) = 35.00% * 120
\n" ); document.write( "25 x + 50 ( 120 - x ) = 4200
\n" ); document.write( "25 x + 6000 - 50 x = 4200
\n" ); document.write( "25 x - 50 x = 4200 - -6000
\n" ); document.write( "-25 x = -1800
\n" ); document.write( "/ -25
\n" ); document.write( " x = 72 ounces 25.00% Solution A
\n" ); document.write( " 48 ounces 50.00% SolutionB
