You can put this solution on YOUR website!
Call the amount of 14% solution he needs to add, x. Then we set this up as
\n" ); document.write( "1(.82) + x(.14) = (1+x)(.31)
\n" ); document.write( ".82 + .14x = .31 + .31x
\n" ); document.write( ".51x = .17x
\n" ); document.write( "x = 3 mL of the 14% solution \n" ); document.write( "

\n" );
