Brings up the question of how one finds the money (6)
I believe the answer is:
raises
'brings up' is the definition.
('raise' can be a synonym of 'bring up')
I can't explain the rest of the clue.
Can you help me to learn more?
(Other definitions for raises that I've seen before include "Increase the amount of a poker bet" , "Lifts or brings up" , "Brings up the subject of a wage increase" , "Takes from a lower to a higher position" , "Salary increases" .)
