Broken Screen Ipod touch gen 4

Ok so ive had my generation 4 ipod since christmas last year i dont have a warranty on it and my niece dropped it on my title floor and it chattered the screen. As you can see in the pic my ipod touch is pretty cracked 😟 I descovered today that the screen is starting to come up on one the sides. If i took it to an apple store How much is it gonna cost me to repair it?
