I was thinking of using cc to compare the answers... But it's generally unheard of for a basic problem to use cc unless it's either specified in the question or in the pretext leading up to the question. And 19.5 isn't an answer anyways.
Yep on cc, especially since I just noticed the OP referred to intperpolating a table rather than using math. Either our understanding of the question is incomplete or none of the answers are correct with 21.6% being the most likely choice. Once you assume there's an error in the question or answers then it cannot be solved - you can only pick the answer most likely to be marked correct. I suspect there may be additional factors that the OP didn't mention.
Well, in the review questions I've been solving I found that the right answer is the closet one. How did you calculate the 224,755.712 ? using F = A (F/A, 21.6%, 2) ???
