how many ounces of pure water must be added to 75 ounce of a 20% salt solution to make a salt solution which is 15% salt?
\n" ); document.write( ":
\n" ); document.write( "Let x = amt of water to be added:
\n" ); document.write( ":
\n" ); document.write( ".20(75) = .15(75+x)
\n" ); document.write( ":
\n" ); document.write( "15 = 11.25 + .15x
\n" ); document.write( ":
\n" ); document.write( "15 - 11.25 = .15x
\n" ); document.write( ":
\n" ); document.write( "3.75 = .15x
\n" ); document.write( ":
\n" ); document.write( "x = 3.75/.15
\n" ); document.write( ":
\n" ); document.write( "x = 25 ounces of pure water to be added
\n" ); document.write( ":
\n" ); document.write( ":
\n" ); document.write( "Check solution using the salt content:
\n" ); document.write( ".20(75) = .15(75 + 25)
\n" ); document.write( "15 = 15 \n" ); document.write( "

\n" );
