$\"18%2B27=45\"$ and that is $\"10\"$ more than $\"35\"$ ,
\n" ); document.write( "(a) so the $\"highlight%2810%29\"$ families counted twice have both a car and a bike.
\n" ); document.write( "(b) Of the $\"18\"$ families that have a car, there are $\"10\"$ that also have a bike,
\n" ); document.write( "so there are $\"18-10=highlight%288%29\"$ families that have only a car, but no bike. \n" ); document.write( "

\n" );
