The three key pieces of information are(1)there are three more students on the track team
than on the baseball team;(2)there are
three more students on the track team than on the
football team (therefore the number of students
on the baseball team and the football team are the
same); and(3)the number of baseball and
the number of football players equals 8. Since the
two numbers are equal, there must be four players
on each team. Now it's easy to figure out the rest.
