Been trying this for 30mins, and I can't get it. I just thought the smart masses at AT would like the challenge. I know there are some people here who have to solve a word problem like this as soon as they see it (me being one, which is why I'm so frustrated )

:beer:- (Cost of superman + 20%) + (cost of spiderman - 20%) = X. See what happens.

Come on, you know he got $36 for the first comic, right? Just multiply the second column numbers by .8 until you get $36. Simple elimination. :beer:
