I have a final assignment for my one precalc college class due today, and the one part of it is just killing me, and I can't figure it out. This is a screen cap of the problem:
I don't know how to solve, well, any of that. Word problems just drive me crazy. >_< I don't even know how to get started on any of that. If some one could at least get me on the right track for those problems, that'd be great.
