Answer:
a) 120 skiers per day
b) 6.25% increase in revenue
Explanation:
a) If the average skier stays 10 days, the average turnover is 1/10 of the skiers per day, or 1200/10 = 120 skiers per day.
__
b) For a stay of n days, the average skier spends ...
50 +(n-1)30 = 20 +30n
and the average spending per day is ...
(20 +30n)/n = (20/n) +30
So, for a 10-day stay, the average skier spends in restaurants ...
20/10 +30 = 32 . . . . per day
And for a 5-day stay, the average skier will spend ...
20/5 +30 = 34 . . . . per day
The change in restaurant revenue is expected to be ...
(34 -32)/32 × 100% = 2/32 × 100% = 6.25%
Restaurant revenues will be 6.25% higher compared to last year.
