Can you show 14 passengers on a DDB as 12 on top 2 on bottom?
NO! 10 passengers is the most that can fit on one level of the DDB.

If passengers decide to move their seat on the bus, does it change the total amount of passengers on the DDB?
No, moving from one level to the other does not change the number of passengers on the bus. 10 on top + 3 on bottom is the same as 8 on top and 5 on the bottom. 2 people left the top and moved to the bottom. 2-2=0 ; no change to the total
