As long as I calculated it right, it should be 9a...

anonymous · Answer

thats why i thought you confused it or something.?

anonymous · Answer

I realize that.. not quite sure how to get around that. I got 9a and I don't think I miscalculated anything.. If I were the one taking this test or completing this homework I would just choose 19a, because there's a 9a in it. (But don't take that advice, I don't want to make you choose the wrong answer, if it is wrong)
