Know how to price my rides?

[Squablo]

I understand that the prestige score is an indicator, but I'm not sure exactly what to price it at based on that.
I guess what I'm trying to ask "what's the equation to price things at because I can't breathe without running numbers through my head."

IMO for some very strange reason, finding the right price is purely a guessing game. my suggestion is to save your park anytime you build a new ride, then test the price by raising it or lowering untill guests seem to be happy paying the most you can charge. Once you figure out the price, reload your save. Then you should write down where each rides price point is so you can remember for next time. Obviously theres different variables like scenery and difficulty level, but once you have the base range its easy to adjust
