This is something you and your parents are going to have to discuss and research.
Costs - you can calculate how much gas is going to cost. Campsites can be anywhere from free to $40 a day. Food costs pretty much the same anywhere. You are going to have to plan an overnight stop of some sort between Seattle and Sacramento, it's too far to drive in one day.
