Problem: Able, Baker, and Charlie are three carhops at the Sonic Drive-In (service at the speed of sound!).

Cars arrive every 55 minutes. The carhops service customers at the rate of one every 106

minutes. However, the customers prefer Able over Baker, and Baker over Charlie. If the carhop of

choice is busy, the customers choose the first available carhop. Simulate the system for 200

service completions. Estimate Able's, Baker's, and Charlie's utilization (percentage of time busy).
