Payments in cash

Hello everyone, please need help. I will rent my appartment and I will receive the payment in the moment on cash. So my question is, which one of these three values on the image should I charge to the client? As far as I understand, I have to charge the green one, since the blue one is comission that I will have to pay to booking, and red one is my actual profits am I right? And if is so, Why the red one plus the blue one doesnt result on the green one?
