If you are looking for an equation,
n - 12 + 5
Cost=$225
Revenue = $75x, x being the number of rooms rented.
R-C=75(35)-225=$2400
Double that
4800=75*x-225
5025=75x
x=67 rooms
One can't just double the number of rooms, because the maintenance fee is constant and doesn't change proportionally. It doesn't change at all.
5 + (8*y) = h
This was the best I could think of, please let me know if I'm wrong.
