Teaching Adults one on one or by group

Does anyone know how much is the appropriate rate in teaching Adults? Does it have to be individually per hour or per group, granting this is an informal invitation from an Adult student or students to teach them privately.

 

All inputs are welcome.

 

Bunch of thanks!
