I'm not sure where you saw 100$.

The economy plan would be more than you would ever need, and it's very cheap.
If you buy that hosting, you will have 5GB of space to do anything you want with it. The domain you buy will point towards this disk space.
Basically, you buy blank space...then upload what you want for a website. You will either need to code your own website, or you will need to upload some sort of software (there's a lot to choose from, just google it).
Hope I helped.
