Hold on, I'll ask Facebook and Twitt- wait a minute, you ask them.

There is no fixed charge with Facebook,
You get to choose exactly which audiences your advert reaches, and as you select a wider audience, the price increases.
There are many ways you can keep actually work to reach the best strategy which suits you.
You can decide a maxium budget per day so you will never pay more than your max bid, but you may pay less. The higher your bid, the more likely it is your advert will get shown. You can also pay per click.

If this hasn't helped try searching the obvious ' Advertise with Facebook '
