Also depends on what kind of bud you're using. It generally takes quite a bit more weed to get one person high when eating it, so keep that in mind. Double what it would ususally take to get you high and you should be fine. Allthough it also depends on how many brownies you're planning to make. Unless you and your buds want to eat a whole tray of brownies then nock yourself out. Otherwise make them potent so you're not eating 4 or 5 to feel anything.
