I went ahead and did this one out, which got me to the correct answer (A). However, if I didn't go into immediate math machine mode, I would have noticed that the only answer it could be is A. We already know that a markdown from 120 to 100 would be a smaller change % than that of 100 to 80, because it's the same change amount, but a bigger denominator.

Just food for thought that could save you a minute or two.
