Donaldson Bed and Breakfast has six available rooms to rent to tourists visiting Niagara Falls. Guests enjoy a comfortably appointed

room with an attached bathroom and the owners provide a hearty breakfast each morning. The owners have calculated that their

typical occupancy rate is $80\%$ per month. The cost to rent each room is $$65$ per occupied room per day assuming a $30-$day month.

Some of this cost is fixed and some variable. During the month of June, the occupancy rate went down to $60\%$ and the total cost to

operate that month was $$7,650.$

Using the high$-$low method, estimate the variable and fixed cost elements of the bed and breakfast's operation in a typical month.

Note: Do not round your intermediate calculations. Round the "Variable cost per room" to $2$ decimal places.

Note: Do not round your intermediate calculations. Round the "Variable cost per room" to $2$ decimal places.

$2.$ Express the variable and fix cost in the form Y$=$ a $+$ bX$.$ Note do not round your intermediate calculations. Round the variable cost per room to $2$ decimal places. $3.$ If the occupancy rate went up to $90\%$ in a particular month, what total cost would you expect to be incurred in that month? Note: do not round intermediate calculations.
