Here's the scenario for building our What$-$if Scenario Model $--$

You are the manager of a gourmet food shop in State College, PA$.$ Your customers love your store, however, your customer satisfaction surveys show that the average customer becomes increasingly dissatisfied after a $2-$

minute wait. On average it takes your cashier $3$ minutes to check a customer out. That means that the service rate per hour is $20$ customers.

At what point do you open another check$-$out line to avoid wait times greater than $2$ minutes, if the customer arrival rate into the queue line is $7,8,9,$and $10$ customers every hour? REMEMBER: Customers will be

satisfied to wait up to and including $2$ minutes, but they will not be satisfied to wait $1-$second more than $2$ minutes.

Let's find the answer and keep your customers happy!
