Reasonable ticket fee announced (4)
I believe the answer is:
fair
'reasonable' is the definition.
(associated in meaning)
I don't understand the remainder of the clue.
Can you help me to learn more?
(Other definitions for fair that I've seen before include "Equitable or blond" , "Considerable" , "Treating people equally" , "Exhibition of commercial or industrial goods" , "light headed" .)
