The minimum is $2,000 if you want to source your own housing (and for example stay with a friend in the area).
The food cost is just fully straightforwardly passed on ($20 for a catered meal is not a lot!), and the rooming is also provided below cost (good luck finding a short term rental for less than $1,500/mo, or even $3000/mo in Berkeley). We are subsidizing this with our own money, this isn't going to make us anything.
Like, man, what are these expectations? Where can you get a month-long hotel experience in a major metropolitan area for less than $3,500 a month? And that is ignoring all of the costs associated with the rest of the program, which will involve a lot of volunteered time from staff with opportunity costs in the hundreds of thousands of dollars a year.
$100/night in Berkeley is not going to get you something pretty, and definitely no food included.
