Consider a small car service station with a full$-$time server and a manager. Arriving cars

have exponentially distributed interarrival times with an expected interarrival time of one

sixth of an hour. The service time is also exponentially distributed with a mean service

time of $5$ minutes. However, if the server is busy and there are cars waiting for service,

the manager inside comes out and helps service the cars. The service time of the man$-$

ager is exponentially distributed with a mean service time of $8$ minutes. Run the simula$-$

tion for $10,000$ hours.

Please demonstrate ARENA simulation model.
