conversations.value: Half of the class consists of 28 students / 2 = 14 students.
  One half of the students have 14 students * 3 notebooks/student = 42 notebooks.
  The other half have 14 students * 5 notebooks/student = 70 notebooks.
  There are 42 notebooks + 70 notebooks = 112 notebooks in total in the classroom.
