Answer:
24 customers per hour
Step-by-step explanation:
The service rate is given by the demand of customers per hour per employee divided by the labor utilization.
If there are two service counter employees on duty, the demand of customers per hour per employee is:
[tex]D=\frac{36}{2}=18\ customers/hour[/tex]
Assuming a 75% labor utilization, the service rate is:
[tex]S =\frac{18}{0.75}=24\ customers/ hour[/tex]
