You$$re a manager at a local CAR RENTAL company tasked with efficiently allocating rental cars across different locations. For simplicity, we$$ll refer to these locations using generic names, and it$$s important to note that all cars are interchangeable in this scenario. Currently, Sites A$,$ B$,$ and C have $8,12,$ and $10$ cars on$-$site, respectively. The demand at Destinations X$,$ Y$,$ and Z is for $9,7,$ and $11$ cars, respectively. Your objective is to determine the most cost$-$effective distribution strategy for these cars, according to the unit transportation costs outlined in the provided table.
