Answer:
She can pay a maximum of $212.50
Step-by-step explanation:
Average price for hotel room is $250 per night
The hotel is offering a discount of 15% on the hotel room price.
If Karen chooses a room at thirteenth floor she can only pay up to $212 for a room per night.
When Karen has paid $250 for a hotel room she gets to know that there is no availability of a room on the floors below thirteenth floor. The price is non refundable. She can ask the hotel for any extra services which can compensate her stay at thirteenth floor.
