If the vending machines are placed together the placement counts as one location.
Example: There is a soda machine and a snack machine that are placed in the same spot of the property.
If the vending machines are in the same location but are in different parts of the property, it counts as seperate locations.
Example: There are 3 machines being placed in one location, but the location has 3 floors and 1 machine is placed in each floor.
