If in one day I earn 350 reputation (capped at 200), and on the same day I offer a bounty of 100, at the end of the day, have I gained 100 or 200 reputation?

You can earn 200 rep with upvotes per day. If you invest some of that in a bounty you can't earn more on that day.
The reputation cap does not mean you can gain 200 rep per day at most (apart from bounties and accepted answers), it means you can earn 200 rep.
It happened to me on the 2013-06-18 here on meta. (How can I link that?) I gave 200 bounty away, I hit the rep cap and in total I only gained 2 points that day.
