In Tennessee the group visited the Grand Ole Opry
and the home of Casey Jones, America's most
legendary railroad man. One of the group members
happened to find a souvenir shop with a great price
on postcards, so everybody decided it was time to
write home.
• The group bought a total of 46 postcards.
. 27 of them had a picture relating to Casey Jones
• The number of cards which had both Casey
Jones and the Grand Ole Opry on them was 6
times the number which had neither.
The number which had the Grand Ole Opry but
not Casey Jones was 5 times the number that
had Casey Jones but not the Grandy Ole Opry.
How many of the cards had neither of
these subjects on them?
