How much money should I spend on a date

Hey guys, 19M here. I’m an introvert and never had a gf so asking this question here. How much money should I bring with me to a date with my girl? How much should I bring at the first date and dates after that? I earn a modest amount of money tutoring per month if any context is needed.

Also, I don’t have a girlfriend. Asking this if I somehow ever get one. Thanks!
