A study done by the largest hotel in the village has shown that skiers spend on average $50 per person on the first day and $30 per person on each additional day in local restaurants. The study also forecasts that due to increased hotel prices the average length of stay for the upcoming 2018/ 2019 season will be reduced to five days. What will be the percentage change in revenues of local restaurants compared to current year (when skiers still stayed for 10 days)? Assume that hotels continue to be fully booked (i.e., on average there are still 1200 skiers in the village). Also assume that the spending profile remains the same, i.e., skiers still spend on average $50 per person on the first day and $30 per person on each additional day in local restaurants. Choose the numerically closest answer.
