Answer: the percent of change from peak season to off-season is 33.33%
Explanation:
During peak season a hotel room cost $135 per night.
During the off-season, the hotel room cost $90 per night.
The difference in price between peak season and off season would be
135 - 90 = $45
Therefore, the percent of change from peak season to off-season is expressed as the change in price divided by the price at peak season × 100. It becomes
45/135 × 100 = 33.33%
