How much would a 2 gb monthly data package cost at Verizon?

I'm going to get the iPhone and I want to know how much it will cost each month to have a 2gb data package. I tried looking on their website and all, all I want to know is how much it will cost a month.

We offer three data packages to choose from, starting as low as $30 per month:
Data Packages for Smartphones
Monthly Data Allowance Monthly Access Fee Rate After Allowance
2 GB $30 $10 / 1 GB
5 GB $50 $10 / 1 GB
10 GB $80 $10 / 1 GB
