3Ds XL repairs. How much would it cost?

I was playing on my 3Ds, then I dropped it. The inside screen cracked and there was black on the screen along with the cracks. I still used it. Later on I was standing on my bed and dropped it again, this time it fell on it's corner where the R button is. The back of it where the R button is, is seperated from the front part. It still works, but I was wondering how much it would cost so I know.
