Dr$.$ Christopher has two options to increase service time in the near future: one is to hire a surgeon with a $$3,000$ weekly payment. The variable cost of serving a patient is $$100$ with an average service time of $100$ minutes. The other is to contract another surgery clinic with a variable cost of servicing a patient of $$700.$ Based on the predicted service time from question $5,$ which options Dr$.$ Christopher should go with? Why?
