How to find out the fair price for an elephant tour in India? [closed]

As a foreigner it can sometimes be hard to judge what is a reasonable cost when the internet is flooded with ads directed at tourists (who are often willing to pay crazy prices due to lack of better knowledge).

Prices I have seen on the internet for 1 hour tours (2 people) literally ranged from $200 to $800. But what price would a local Indian resident expect to pay? If prices vary significantly by region, how can I get a rough estimate for whatever region I'm traveling in?

To prevent the question being opinion-based: I don't care about the "cheapest" option, nor do I care about a specific location or a specific cost. All I want to know is beyond what price is something exclusively geared towards tourists and should be ignored.
