I am guessing that you have to say whether the statement is true, false, or whether it can't be determines from the text. Anyhow, the text extract says her meals cost about the same as takeaway, but it doesn't say whether she offers takeaway. She might offer doggie bags for her guests though. It doesn't mention that either but most, if not all, restaurants in America allow you to take leftovers home in a doggie bag and if she is really treating this as a restaurant, then I could logically see her offering that too.
Anyhow, we call it "takeout" instead of "takeaway" in my part of the US. For instance, "Do you want to order takeout tonight?"
