A Bank has two types of customers: merchant customers andregular customers. The meanarrival rate for each type of customer is 15 per hour. Both typesof customers currently wait inthe same line and are served by the same tellers with the sameaverage service time. However,Sally is considering changing this. The new system she isconsidering would have two lines—onefor merchant customers and one for regular customers. There wouldbe a single teller servingeach line. What would be the average waiting time for each type ofcustomer before reaching ateller? On average, how many total customers would be in the bank,including those currentlybeing served?
