conversations.value: The total pay per employee in a day is 12*10 = $120
  An employee works for 5*4 = 20 days in a month.
  The total amount of money paid to each employee monthly is 20*120 = $2400
  When the number of employees increased to 500+200 = 700 after the new hires in August.
  The company pays a total of 700*2400 = $1680000 per month to its employees
