does bu ne karda, kac para and hepsi ne karda mean how much?

what does ne karda mean?

does baska mean do you want anything else? what other phrases should i listen for if someone asks the same question.

to reply nothing else is baska birsey istemiyorum correct? or is there a better phrase

I think:
"bu ne karda" should be "bu ne kadar" (how much is this)
"kac para"= "kaç para" (how much money)
"hepsi ne karda" should be "hepsi ne kadar" (how much is everything/all of them)

ayla

thank you very much for your quick reply
