please show step by step how you would solve this without using a program thank you. for both questions. (calculate it)

Ticket Counter Simulation Now let's use a queue to simulate the waiting line at a movie theatre The goal is to determine how many cashiers are needed to keep the average wait time below 7 minutes We'll assume: - customers arrive on average every 15 seconds - processing a request takes two minutes once a customer reaches a cashier Q4 (10): Please run the ticket counter simulation code with following parameters: a. Number of customers per day =200 b. Single Customer Service Time =5 minutes c. A customer arrives in the system every 20 seconds How many cashiers are needed to keep the average customer wait time below 10 minutes
