TOPIC: Scenario Question

I have many different events throughout the year.
All these events have different costs for different attendee types.
There are 3 different attendee types, Adult, Child1 and Child2.
If event1 charges $5 for Adult and $10 for Child1 & 2,
and event2 charges $45 for adult and child1 & 2,
and event3 charges $15 for Adult and $22.50 for child1 and $25 for child2...
how can i accomplish this?

Any suggestions regarding my scenario?

I've accomplished similar things with using fields, and if necessary conditional fields. The video tutorials on fields are really helpful; start there, do some testing. It's helpful for me when I have several fields and/or conditionals fields to draw out the hierarchy on paper first.
