Food price (4)
I believe the answer is:
fare
I believe this is a double definition.
'food' is the first definition.
(fare is a kind of food)
'price' is the second definition.
(I have seen 'Price of passage ' mean 'fare' so perhaps 'price' could also mean 'fare')
(Other definitions for fare that I've seen before include "Food for the cost of a journey" , "Food provided in fear" , "Meal" , "Paying passenger" , "(Person paying) price for travel" .)
