"The bill is ten dollars."
Translation:He ʻumi kālā ke kāki.
He is typically used as a prefix before a number between 10-99. See slide three of this lesson on nā helu — numbers. https://www.slideshare.net/malama777/helu?qid=e221adf5-445f-484b-afca-7755ae8488e5&v=&b=&from_search=14
I was puzzled by these words — pila vs kaki. I would say pila should be accepted. Indeed on another forum Lee posted the following:-
Ka pila = the bill or check like at a restaurant
ke kaki = the cost or price like at a store
My own research so far suggests they are interchangeable— ha haumana au.
My experience with DL is that when more than one translation is given in the drop-down menu, choosing the top one USUALLY gives you the correct answer. Recently, however, they've wised up to this situation, and have started preferring random choices on the drop-down, so I keep a running list and refer back to it for specific situations. This helps me only minimally.
