In a motal there are 30 rooms. Motal owner charges 20$ per day. The owner is thinking to increase the rent by 1 dollar but if he increses the price by 1 dollar one room will be vacant(emptied).
Daily service and maintanance to clean the room will cost c=x^2-60x+900 find the break even point and find out how many rooms will be vacant and how many rooms will be filled.
