Charge, fare (3)
I believe the answer is:
fee
I believe this is a double definition.
'charge' is the first definition.
(I know that fee is a type of fixed charge)
'fare' is the second definition.
(thesaurus)
(Other definitions for fee that I've seen before include "Cost" , "Amount paid for job" , "(Entry) charge" , "Sum payable to, say, barrister" , "Payment to a professional for services" .)
