Kitzbuhel is a beautiful village located in the Austrian Alps, known for its legendary downhill ski race. On average, over the course of the winter season, $6,000$ tourists are in town. The average length of stay of tourists is $8$ days. The survey also concludes that tourists spend on average $$40$ per person on the first day and $$30$ per person on each additional day in local shops. The study also forecasts that, because of the increasing prices, the average length of stay will be $5$ days the next winter.

Assuming the city continues to be fully booked, what will be the percentage change in revenues compared to last winter $($when tourists stayed for $8$ days$)?$

Answer as an integer
