Need To Sit Down For This Math

(I work at a large movie theater company and on this particular occasion, I am working Guest Services. This conversation takes place over the phone.)

Me: “Thank you for calling [Movie Theater]. This is [My Name]. How may I help you?”

Guest: “Hi, um, I was wondering about the 7:40 showing of Mockingjay. Is it sold out or are there seats available?”

Me: “Well, that showing is in a larger movie house. So, we still have 516 seats left out of 520 seats.”

Guest: “Oh, um, okay. Are there enough seats for five of us to sit together?”

Me: “Uh… Yes, there are enough seats for five of you.”
