On average each customer service representative can service 7 customers every twenty minutes at a cost of salary and benefits for a bank teller is $19.50 per hour. The bank is open 8 hours each day. If it has been estimated that the waiting time cost per hour is $72.00 per hour in line. The branch operates one lane for the entire 8 hours per day but opens a second lane during peak times four hours per day. Assume the arrival rate for off-peak hours is 5 customers every twenty minutes and the arrival rate for peak time increases to 6.5 customers every fifteen minutes.
