Ann, Barry, Charlene, Doug, Evelyn and Fred went to
lunch to celebrate Evelyn's and Fred's birthdays. Each
person's meal cost the same amount. Evelyn and Fred were
being treated for their meals, but each was to chip in
equally for his or her share of the other's lunch. (So, Evelyn
paid a little towards Fred's only.) If the bill came to $54.00
how much should each person pay?
