Rozalin, do check the sites Mani gave... Esp. the part on "Elasticity" in wikipedia... They are very resourceful...
If still, you do not understand, let us know...
Mani, thank you... Though you do not study Business, you did make provision in case all the members here were busy.... That's a sign of maturity... 
Yeah thanks, that was the point of my post.
I am just tryna help the way I can. That's my job.
Thanks Alpha
- at least
you understand.
[[EDIT]]: @Rozalin - Thanks for the +rep. Hope you cleared your doubt.
(nvm, that was for your Bio Questions - just remembered).
Mani, for the Love of Allah, give a direct answer. If you don't have the time to do so, then dont answer. Do not answer if you are not a student of this subject.
I take out precious time to actually google efficiently and find whatever I think is most relevant. I feel it is my duty. That is why I do not say "THIS IS THE ANSWER". I just say check this out, maybe this will clear your doubt.
However, I guess you are right. I do not expertise in Business or whatever.
Anyway. . .
