OK, you're still wrong, but I see where you are going. The +1400% doesn't work that way at all. The profit is a bonus percentage to the gold production of the passengers, not a modification to the number of passengers sent. What I would believe, is that you are using the Trainroute Planner slots. Each additional destination, past the first, adds an additional 15% passengers from the base amount that the train would normally deliver. Or, if you'd prefer a table...

For your example, I derived the base number of as 14* + 6* =. It's not entirely accurate, but it should be close enough.

Using my example above, sent to 8 destinations would still only expand out to 2.05 *  =. That still falls short of ..by a lot...

Now, if you want to involve profit, then you get into a conversation of what would be called "equivalent passengers", which takes a base profit for a generic passenger and applies the profit bonus to determine what an equivalent number of passengers would be. That's a much more involved discussion, particularly with sets, but the lazy way to do it is just compensate by applying the profit to the passenger amount. Even with calculations of the "equivalent passengers", you still don't change the number of passengers sent as shown in the table above.
