Problem
Rapidfire comic-making, here it is! I'm getting used to GIMP! In fact, this is the first comic that was executed 100% in GIMP. (I mean 'executed' as in 'realized' or 'accomplished', not as in 'killed by the state'.) So! This is a rare moment when Americrayon shares my experiences. I had this exact homework problem*, and I was so tempted to give the answer Americrayon came up with, but I gave in and wrote the correct answer instead. (I'm trying to pass the class.) It also raises the question: How old is Americrayon? I will tell you that she's old enough to work in an office job and still be taking Calculus. Hmmmmm?
