Q$2(14$ points$)$ The Garland DPS processes DL renewal applications through the following three

steps:

The customer registers with the receptionist, who updates the customer's information

in the database. This step takes $2$ mins per customer.

The customer then visits one of two cashiers to pay the DL renewal fee and fills out the

application form. This step takes $6$ mins per customer.

Finally, the customer goes to one of three license processing stations where the

customer's picture is taken and the license is printed. This step takes $12$ mins for each

customer.
