[Solved] Calculating price for childs in Complex Tarif

Hi!
I have problems when calculating prices for children.
For example: there is a room that accommodates 3 ​​adults and 3 children.
Rate Type: per person per night.
Tariff details: 1 adult - $ 100; 2 adults - $0; 3 adult - $ 20; 1 child - $10; 2 child - $10; 3 child - $10

So if I choose:
2 adults = 100 $
3 adults = 120 $
1 adult = 100 $
but if i select adults with childs it calculates price for adults and for all 3 childs. For example:

2 adults + 1 child = 100 + 30 = 130$
3 adults + 1 child = 100+20 + 30 = 150
1 adult + 3 child = 100 + 30+30+30=190

So it summarizes the tariff for all childs, and multiplied by the number of children. Can you tall me where can i find calculation formula/ Thank you!

No, my childs all the same ages

What if i have family with 2 adults and 2 childrens of the same age?

Thx!

Thank you!

Now I see the solution to the division of the tariff on the number of children

hello
I have a problem calculating the price with the children.
rate sought: adult 1 = 125 € adult 2 = 25 € child 1 = 25 € child 2 = 25 € = 25 € = 200 €
the total price calculated by solidres 150 € children are not taken into account.
I may have made a configuration error or there is a technical problem.
Thank you for helping him.
kind regards
