You can put this solution on YOUR website!
How many ml of a 70% acid solution must be added to a 30% acid solution to get 100 ml of a 40% acid solution?
\n" ); document.write( ":
\n" ); document.write( "Let x = amt of 70% solution required
\n" ); document.write( "then
\n" ); document.write( "(100-x) = amt of 30% solution required
\n" ); document.write( ":
\n" ); document.write( ".70x + .30(100-x) = .40(100)
\n" ); document.write( ":
\n" ); document.write( "You should be able to do this now. \n" ); document.write( "

\n" );
