Question 2 1 pts A customer support call center for a cell phone service company has an average waiting time of 5 minutes. Due to some network issues, the call volume (i.e., the number of calls arriving at the call center per hour) is expected to increases by 50%. Keeping the staffing level and the average time spent in processing a call at the same level, this increase in call volume will have to the following impact on the average waiting time: The average waiting time will not change. O The average waiting time will increase by less than 50%. The average waiting time will increase by 50%. The average waiting time will increase by more than 50%.

Explanation / Answer

2. The Average waiting time will increase by 50%

If we assume that there are 100 calls initially which had waiting time of 5 minutes. 50% increase in calls mean 150 calls and as the staffing level and average time spent in each call is same then New Waiting Time - ((5*150)/100) which gives 7.5 minutes waiting time which is 50% increase in waiting time

9. The correct answer is 2616 and the option is not listed. One bag of choclate chip costs $80, therefore 80 bags will cost 80*80= $6400. The ordering cost is $20/order, there are two orders, therefore ordering cost is $40 and the inventory holding cost is 40%. Now, 40%of 6440 = 2576. According to the question total cost of ordering and holding inventory is 2576+40 = $2616
