To reduce 16 ounces of a 18% saline solution to a 10% solution, how much distilled water (to the nearest tenth oz.) should a nurse add?
\n" ); document.write( ".
\n" ); document.write( "Let x = ounces of distilled water to add
\n" ); document.write( "then
\n" ); document.write( ".18(16) = .10(16+x)
\n" ); document.write( "2.88 = 1.6+.10x
\n" ); document.write( "1.28 = .10x
\n" ); document.write( "12.8 = x
\n" ); document.write( ".
\n" ); document.write( "The nurse should add 12.8 oz. of distilled water.
