Getting my hair dyed, how much should it cost?

Hey! So I just moved to Austria a couple months ago and I am not really sure about prices of stuff. I currently have red-ish pink hair that's kind of like a little bit of an onion color. By the way my hair is quite short. I want to get it re-dyed into silver since I am not a big fan of the color and my roots are also coming in. I know how much it would cost where I come from but not sure how much it would cost here to be honest, could you help me out?
