Quechua varies a lot across dialects, and there are a few different ways to say "thank you" in different situations. Here are two ways to say "thank you" in the Cuzco dialect of Peru:
Añaychayki(ah-nyai-chai-kee)
Sulpayki(sool-pai-kee)
The "ki" at the end of the words means "you," so you can also just say "sulpay" or "añaychay" which are more informal, like "thanks."
"Hello" in Quechua is "Rimaykullayki" and "goodbye" is "Allinllachu."
