How would you model the average number of high priority items waiting in line for service in a system with the following data?

Priority	Average Arrival Rate (exponential interarrival times)
high	3 per hr
low	5 per hr
num of servers	5
service rate	2 per hr (exponential service item)

a. using a Linear Programming model to optimize the number of iterations

b. Using the information and the RAND() function to generate the average arrival rate based on the priority.

c. Using the information and the RAND() function to generate the priority based on the service rate.

d. none
