conversations.value: When hired, each employee is paid $15*40 = $600 per week.
  The total earnings of a contracted employee in a month are 4 weeks * $600 per week = $2400
  Paying 40 employees, the company paid 40*$2400= $96000 to all of its contract employees in May.
  In June, 1/4 of the employees' contracts expired, that is 1/4*40 = 10 employees.
  The total number of employees whose contracts were valid in June was 40-10 = 30 employees.
  The total amount of money paid to the contracted employees in June is 30*$2400 = $72000
  In the two months, the company paid a total of $72000+$96000 = $168000
