conversations.value: Find the answer to the math problem: Casey is trying to decide which employee she wants to hire. One employee works for $20 an hour. The other employee works for $22 an hour, but Casey would also get a $6/hour subsidy from the government for hiring a disabled worker. How much money per week would Casey save by hiring the cheaper employee, if they both work 40 hours per week?

conversations.value: First find the weekly cost of the first employee: $20/hour * 40 hours/week = $800/week
  Then find the hourly cost of the second employee after the government subsidy: $22/hour - $6/hour = $16/hour
  Then find the weekly cost of the second employee: $16/hour * 40 hours/week = $640/week
  Then subtract the smaller weekly cost from the bigger weekly cost to find the difference: $800/week - $640/week = $160/week
