How much does it cost to get your hair dyed in a salon like Supercuts?

I have naturally dark brown hair but I have it dyed in a medium warm brown color. I want to dye it dirty blonde but I would like to know around how much would the cost for that be. My hair's length is just below my shoulders in layers, straight, and its not too dense. I also live in California I'm not exactly sure if it's more expensive here, but if anyone can please let me know around how much it be I'd really appreciate that. Thank you :)
