Answer:
10
Total
Marginal
Explanation:
Marginal utility is the change in utility that occurs from consuming one extra unit of a good.
Marginal utitiy = 55 utils - 45 utils = 10 utils
Total utility is the utility derived from consuming a good or service.
When :
1. Total utility is 45 , marginal utility is 15
2. total utility is 55, marginal utility is 10
This shows that as total utility increases, marginal utility falls.

Participants will now be selected from each group at random to participate in the survey.
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.
