You are describing where I live only that temperature is a bit low. I'm sorry to say it is neither one.
t_daily = t_average +/- 5
The highest temperature would be
t_daily = t_average + 5
t_daily = 1 + 5
t_daily = 6
================
The Lowest temperature would be
t_daily = t_average - 5
t_daily = 1 - 5
t_daily = - 4
Sounds about right for December.
The main floor has 26 rows of 29 seats each, that is 26*29 = 754 seats
And in the balcony there is 8 rolls of 23 seats, that is 8*23 = 184 seats
So the difference is 754 - 184 = 570
Then the main floor has 570 seat more than the balcony
