domain 2 Domain Names

[deannam]

I have had these two domains for a while but haven't had time to do much with them:

http://webadvertisinganswers.com
http://webadvertisinganswers.info

What are they worth?
Should I sell them together or separately?
Should I develop them a bit more and let them age?

Thanks, I'm very new to this!
