A 90-room motel has an average room rate of $64 and average occupancy of 77%. Its fixed costs are $800,000 a year, and its variable costs total $500,000.

The owner wants to increase operating income from current level to $250,000. She decides to do the following adjustments:

• increase price by $6
• spend $30,000 more per year on marketing to compensate for the higher room rate
• To motivate the staff, the owner also set a $2,000 reward to the best employee
• Send guest fruits to each room, which costs $5 per room

How many rooms does she need to sell per night?
