Rental service has multiple branches throughout the city. Each branch has a limited number of different kinds of vehicles. Each vehicle can be booked with a predefined fixed price. Each vehicle can be booked in multiples of 1-hour slots each. (For simplicity, assume slots of a single day)

Onboard a new branch with available vehicles. Onboard new vehicle(s) of an existing type to a particular branch. Rent a vehicle for a time slot and a vehicle type(the lowest price as the default choice extendable to any other strategy). Display available vehicles for a given branch sorted on price. The vehicle will have to be dropped at the same branch where it was picked up. Bonus question: Dynamic pricing – demand vs supply. If 80% of cars in a particular branch are booked, increase the price by 10%.
