Boss monsters percentage

Not sure if this is a place for game mechanic questions, but I was wondering if the bonus cash the boss gives is additive where it’s 10%+10%=20%, or if it’s a percentage of the remainder like first 10%, second dragon is only 10% of the 90% left equaling only an additional 9% meaning a bonus of 19% and then nothing dragon adding 8.1%.

Any information on how the math is structured would be appreciated. Please and thank you.

I do believe that it does add 10% for each boss obtained , so if u have 3 of them you would get 30% more gold from habitats, 4 = 40%... Etc . And Overlord boss dragon does Double the effects for boss dragons so you would get 20% each if you have it .
