In my undergrad, when I was living in dorms, it also came with a meal plan (I think ~2 meals a day covered). So for in state, 10-15k was tuition. The rest was rent + meals. So 15k / 12 = $1250 a month, which is not cheap, but considering it includes food is really not bad at all.
But you can't divide it by 12 since school is only in session for roughly 9 months. During summer session you're on your own for food and housing. That makes it more like $1666/month. That's nuts.
