conversations.value: The first 5 students turned in a total of 2 * 5 = 10 pages.
  The next 5 students turned in a total of 3 * 5 = 15 pages.
  The last 5 students turned in a total of 1 * 5 = 5 pages.
  In total there are 30 pages turned in by the students.
  For the 15 students, the average page count per essay is 30/15 = 2 pages.
