Problem $1$: Global Vaccination Passport $($GVP$)$

GVP is an agency that certifies COVID$-19$ vaccination status for international tourists, mostly tourists living in North America $($US and Canada$)$ who want to travel to Europe. The company receives applications containing local vaccination documentation. After certifying all information, GVP provides a QR$-$code that is accepted by many countries in the EU$.$

Based on three months of operations in the Spring of $2021,$ GVP categorizes their cases into the following two groups:

$$ Group $1($people vaccinated in Canada$)$: $20$ percent of cases

$$ Group $2($people vaccinated in the US$)$: $80$ percent of cases

There are $500$ applications uniformly arriving over a ten$-$hour workday. The workflow looks as follows:

$$ The process starts with an administrative support person scanning all files. Five administrative support persons are on staff. Scanning takes $2\mathrm{.}5$ minutes per application.

$$ One certified clinician from Canada, who processes only applications for Canadian customers takes $2$ minutes per application and only handles applications from people vaccinated in Canada $($one physician$).$

$$ Three certified clinicians from the US process applications for people vaccinated in the US$.$ It takes $1\mathrm{.}5$ minutes per application.

$$ All applications then go back to the administrative support persons $($the same group of five mentioned above$),$ who then take another $1$ minute per application to activate the QR code.
