I need help with the second question

Lavilla is a village in the italian Alps. Glven its enormous popularity among Swiss, German, Austrian, and italian skiers, all of its beds are always booked in the winter season and there are, on average, 1,050 skiers in the village. On average, skiers stay in LaVilla for 10 days. How many new sklers are arriving-on average-in Lavilla every day? A study done by the largest hotel in the village has shown that sklers spend on average $90 per person on the first day and $70 per person on each additional day in local restourants. The study also forecasts that-due to increased hotel prices-the average length of stay for the 2003/2004 season will be reduced to 4 days. What will be the percentage change in revenues of local restaurants compared to last year (when skiers still stayed for 10 days)? Assume that hotels continue to be fully bookedl (Round the answers to 1 decimal place.)
