conversations.value: Half of 32 tables is 32*(1/2) = 16 tables
  16 tables have 2 chairs each for a total of 16*2 = 32 chairs
  5 tables have 3 chairs each for a total of 5*3 = 15 chairs
  There are 32-(16+5) = 11 tables left
  11 tables have 4 chairs each for a total of 11*4 = 44 chairs
  The total number of chairs is 32+15+44 = 91 chairs
