I was at Darchei Binah Sister school and I had to pay $50 for dorm utility fee to get supplies to use to clean the dorm when it was my toranut job and $150 for laundry fee for the privilege of doing two loads of laundry a week while I was there.
If you need to provide yourself with multiple meals a day, then I would say you would need $100 a week so that you aren’t starving…
