how many gallons of water must be added to 20 gallons of 15% salt solution
\n" ); document.write( "if the resulting solution is to only contain 11% salt
\n" ); document.write( ":
\n" ); document.write( "Let x = amt of water required
\n" ); document.write( ".15(20) = .11(x+20)
\n" ); document.write( " 3 = .11x + 2.2
\n" ); document.write( "3 - 2.2 = .11x
\n" ); document.write( ".8 = .11x
\n" ); document.write( "x = $\".8%2F.11\"$
\n" ); document.write( "x = 7.273 gal
\n" ); document.write( ":
\n" ); document.write( ":
\n" ); document.write( "See if that is true, the amt of salt should be the same
\n" ); document.write( ".15(20) = .11(27.273)
\n" ); document.write( "3 ~ 3.00 \n" ); document.write( "

\n" );
