You can put this solution on YOUR website!
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.
