You can put this solution on YOUR website!
Call the amount of 6% solution x.
\n" ); document.write( "Then the amount of 20% solution would be 70-x.
\n" ); document.write( "We then set it up like this:
\n" ); document.write( ".06x + .20(70-x) = .12(70)
\n" ); document.write( ".06x + 14 - .20x = 8.4
\n" ); document.write( "-.14x = -5.6
\n" ); document.write( "x = 40 ounces at 6%
\n" ); document.write( "
\n" );
