This question already has an answer here:
It is implied in HP books that Hermione Granger is reasonably affluent, compared to eg. Ron Weasley.
At the start of Prisoner of Azkhaban, she had 10 galleons left to spend after purchasing what was needed for school.
Is it indicated anywhere in books, how she got any wizarding money at all, her parents being muggles? Were they made aware of money needs by the school and were given enough information to arrange exchange with Gringot's?
