A solution of salt and water contains 18 ounces of pure salt and 36 ounces of water. How many ounces of water must be added to obtain a 24% pure salt solution?
\n" ); document.write( ".
\n" ); document.write( "Let x = amount of water to be added
\n" ); document.write( "then
\n" ); document.write( "\"amount of salt\" = 24% of \"total volume\"
\n" ); document.write( "18 = .24(18+36+x)
\n" ); document.write( "18 = .24(54+x)
\n" ); document.write( "18 = 12.96 + .24x
\n" ); document.write( "5.04 = .24x
\n" ); document.write( "21 ounces = x (amount of water to be added)
\n" ); document.write( "
\n" ); document.write( " \n" ); document.write( "
\n" );
