How would I use the OM server to solve the first problem and follow up the second? Or is there a different method?

1: The Frisco Roughriders need help with determining which of the following queuing systems is better for their new food vending area. They have the option of installing a two server system that has less automation or a new one server system in which drinks are automatically filled. They have 1 person per minute show up. The service rate for the automated system is 100 customers per hour and each server for the 2 server is 40 customers per hour.

They have a few key metrics that they are trying to determine and need your help in deciding which system to install:

a. probability that no one is in line

b. total number of people in the system

c. total wait time in the system

2: The next phase of the Roughrider's decision is based on the total cost of waiting. Using all the same information from the problem above, what is the total cost for each system if they cost of waiting is $30 per hour for both systems, the single server system costs $38 per hour to lease, and the cost per server in the 2-server model is $15 each.

Based on this information, what is the cost for each system?
