The local Department of Motor Vehicles issues new licenses and renews licenses. $($See the diagram below.$)$ The office receives $110$ customers per hour. All customers see a receptionist first. The receptionist directs them in one of three directions: $75$ percent go directly to issue license $($staffed by $9$ workers$)$ where a new photo and license are done, $15$ percent are required to take an eye test $($staffed by one worker$),$ and $10$ percent must first take a multiple$-$choice electronic written test $($on one of three computers$).$ Only $85$ percent of people pass the eye test and the remaining $15$ percent exit. The customers who pass the eye test proceed to the written test where $10$ percent of the people fail it$,$ while $90$ percent pass the test and are issued a license.
