To reduce 16 ounces of a 25% solution of antiseptic to a 10% solution,
\n" ); document.write( "how much distilled water should a nurse add?
\n" ); document.write( ":
\n" ); document.write( "Let x = amt of distilled water
\n" ); document.write( ":
\n" ); document.write( "A simple equation
\n" ); document.write( ".25(16) = .10(x+16)
\n" ); document.write( "4 = .10x + 1.6
\n" ); document.write( "4 - 1.6 = .1x
\n" ); document.write( "2.4 = .1x
\n" ); document.write( "x = \"2.4%2F.1\"
\n" ); document.write( "x = 24 oz of distilled water
\n" ); document.write( ":
\n" ); document.write( ":
\n" ); document.write( "Prove this by seeing the amt of antiseptic is the same (only the % changes)
\n" ); document.write( ".25(16) = .10(24+16)
\n" ); document.write( "4 = .1(40)
\n" ); document.write( "
\n" );
