[Iowa] In bar after 10 ticket - U21

I am under 21 and got an "in bar after 10" ticket and was looking for some insight about how it will be handled. One specific questions is about the amounts written on the ticket. There are four categories, Scheduled Vio/Fine ($300), Surcharge ($105), Court Costs ($600), Total Fine/Costs ($465). How do these charges get to $465 for the total?
