conversations.value: In a factory, there are 300 employees. 200 of them earn $12 per hour. Of the rest, 40 of them earn $14 per hour. All others earn $17 per hour. What is the cost to employ all these people for one 8-hour long shift?
  Give me a solution to this problem

conversations.value: The cost of the 200 employees is 200 employees * $12/employee/hour = $2400 per hour.
  The cost of the 40 employees is 40 employees * $14/employee/hour = $560 per hour.
  The rest means 300 employees - 200 employees - 40 employees = 60 employees.
  These 60 employees' employment costs are at 60 employees * $17/employee/hour = $1020 per hour.
  So in total all employees earn $2400/hour + $560/hour + $1020/hour = $3980/hour.
  During an 8-hour shift, this cost would be at 8 hours * $3980/hour = $31840.
