Operations research: Queuing theory using TORA

Layson Roofing Inc. installs shingle roofs on new also old residences in Arkansas. Prospective customer's requests the service randomly at the rate of nine jobs per 30-day month also are placed on a waiting list to be processed on a FCFS basis. Homes sizes vary however it is fairly reasonable to suppose which the roof areas are uniformly distributed between 150 also 300 squares. The work crew can usually complete 75 squares a day. Determine the subsequent:

(a) Layson's average backlog of roofing jobs

(b) The average time a customer waits until a roofing job is completed

(c) If the work crew is increased to the point where they can complete 150 squares a day, describe how will this affect the average time until a job is completed?

I need help in how to enter this into TORA, and how to interpret the results.
