EDIt : Oops, see my reply.

Hello,

I am on the last problem of an assignment I have to do and I have become stuck on this seemingly simple problem. It may not even look like it belongs in Calculus, but it got assigned in my calculus class. I have tried everything, looked in books and online and can't figure the damn thing out.

Here it is,

Given a price-demand equation,
$
p + 0.005x = 30$

a) Express demand x as a function of price p.

This is just the first step and I am only asking for help with the first step because I am hoping that once someone is able to explain it to me, that I will be able to work the rest out. I would be very grateful if anyone would help me, I've spent a LOT of time trying to figure this seemingly easy problem out.
