conversations.value: There are 90 students who have lunch during period 5. Today, two-thirds of the students sat in the cafeteria, while the remainder sat at the covered picnic tables outside. But some yellow-jackets were attracted to their food, and so one-third of the students outside jumped up and ran inside to the cafeteria, while 3 of the students in the cafeteria went outside to see what all the fuss was about. How many students are now in the cafeteria?
  What is the solution?

conversations.value: Originally, there were 90*2/3=60 in the cafeteria.
  Originally, there were 90-60=30 outside the cafeteria.
  Then 30*1/3=10 ran inside
  The number of students inside the cafeteria grew by 10-3=7.
  There are now 60+7=67 students in the cafeteria.
