A small local retailer has two check-out counters available; however, only one check-out counter is currently being used on a particular 8-hour shift. Customers arrive at an average rate of 8 per hour. The person currently working at the check-out counter is capable of serving an average of 10 customers per hour at a cost of $25 per hour. The manager has received numerous complaints from customers threatening to take their business to a local competitor who offers faster customer service. The manager has estimated that the cost of waiting is $50 per hour Option 1: Use both check-out counters, which would require hiring an additional person capable of serving an average of 10 customers per hour. The estimated cost for operating each check-out counter would be $25 per hour. All other parameters would remain the same. a. What is the average number of people that would be waiting in line to be served? b. What is the average amount of time that a customer would spend waiting in line to be served? c. What would be the total daily system cost?
