\n" ); document.write( " $\"D%5BS%5D=30%2At\"$
\n" ); document.write( "For Jane,
\n" ); document.write( " $\"D%5BJ%5D=20%2A%28t-3%29\"$
\n" ); document.write( "where t is measured from when Sue left.

\n" ); document.write( " $\"30t%2B20%28t-3%29=490\"$
\n" ); document.write( " $\"30t%2B20t-60=490\"$
\n" ); document.write( " $\"50t=550\"$
