请问:We'll get one hundred yuan_____.

for all不是固定词组,没这个用法啊.
at all用在否定句中:
1) not...at all=not a bit 根本不
如: I'm not hungry at all.
2) Not at all. 不用谢/没关系
如: Thanks. Not at all.
I'm sorry. Not at all.
2. at all用在疑问句中,表示"到底,究竟"=on earth
如: Did you sleep on the plane at all?
3. at all 用在肯定句和条件从句中,表示"居然,竟然；既然"
如: If you want to do it at all, do it well.
He is very lazy, but he passed the exam at all.
after all是毕竟的意思.
in all是总共的意思.
翻译：我们总共将得到100元.
