Pricing Options In A Single Ad In Mutlivendor Market Place

[mikirimiki]

I've got some questions for you.
My idea is tol ticket's Museums in a multivendor market place
Museum sell their ticket on my website
In few words I would need a flexible prices module.
For example: if a Museum have different prices for children, adults,
groups, and so on, my user will need a way to insert different
prices, and finally get a Total cost.
Example:

Adults € 8.00
Family ticket (2 adults + children under 17 years old) € 16.00
Children under 6 years free, and so on..

Is possbile do this?

Thank you very much
