Just a heads up Kim, it's generally a good idea to explain the question before necessarily giving them the answer and let them logically infer what it is. I don't want to shove words in anyone's mouths but from my understanding, the purpose of the site is largely to coach people through how to do problems. Anyways, thanks dude.
