*screams* AS Levels! (Need Economics help...)

I doubt anybody here is going to be able to help, as the majority of you are doing SATS and GCSEs, but if ANYBODY is doing Economics AS could you PLEASE explain price elasticity of supply? My equations never add up. I'm also a tad confused about incidence of tax. Damn thing. :X

I'm doing economics (but I don't live in the Uk so the whole system is different).

Unfortunatly, I don't get price elasticity either. :(

I do business studies but we're not up to that yet. still doing GCSE lol
