How much should I add to the budget?

S • 💏💑😍
I'm a big planner and I like things set. I'm looking into apartments for me and my boyfriend when I start college. The apartment I'm really liking right now is $475 a month. If we combined worked 30 hours a week we'd make $240 at $8 a hour. If we both worked 30 hours a week it'd be $480 a week. I think us each working 15 hours a week on top of school would be better so that'd be $960 a month. Taking out rent $485. Or it is possible for both of us to work 30 hours a week brining in $1,960 a month. How much should I take out for things like food, gas, and utilities? I'm really trying to decide if I'm being crazy or if this, my dream, can actually happen.
