The company is analyzing to deploy electric cargo bikes (e-bikes) for their delivery operations in downtown. The characteristics and delivery conditions of downtown are such that e-bikes make a lot of sense. However, further analysis is required to assess their convenience from an economical point of view. For this purpose, you are asked to determine the total delivery cost that would be incurred using these new electric vehicles.

A preliminary analysis showed that one cargo e-bike has enough capacity to fulfill the daily demand of any given zone. The table below shows the (X, Y) coordinates of the zone's centers and the area (in squared Km) of each zone. Additionally, it gives information about the number of customers and the number of bottles of water ordered that will be attended on an average day.
