Philosophy, AA, AC, DA, DC?

Question

I'm trying to learn how to figure out which form Conditional arguments are and disjunctive arguments are. And whether they are valid or not. I can determine the arguments form, and thats it. So..

This sentence: If you can't reduce our monthly cell phone bill by at least $15, then it is not worth the hassle of changing your service provider. I just calculated that the montly saving should be only $10 at best, so it is really not worth the hassle of changing your service provider.

Thats conditional, right? But which form is it? AA, AC, DA, DC? and is valid or invalid? And tell me how you determined it so I can learn. Thanks..
