Thank you for your feedback!

You're right that in a real-life scenario, it may not be practical to have half a cook, and it may be necessary to adjust the number of dishes being cooked or the number of friends invited based on the available resources.

Regarding the issue of having 5 rooms with 6 cooks and 1 room with 6 cooks at half capacity instead of 7 cooks at half capacity, I apologize for any confusion that may have caused. My response was based on the information provided in the question, and I tried to calculate the number of friends available to cook based on the given constraints. However, I see now that it may have been more practical to adjust the number of cooks in the last room to 7 at half capacity instead of 6.

Thank you for pointing out these issues, and I'll try to take them into account in future responses.
