Answer:
People should disregard schooling and thus work in the entire life period.
Explanation:
Condition 1--- Work throughout the 4 periods
The NPV = 
= 27,272. 7 + 24,793.3 + 22,539.4 +20,490.4
= 95,095.8
Condition 2 - Attend school and work later
The NPV = -28,000 + 
= -28000 + 41,322.31 + 37,565.7 + 34,150.6
= 85,038.61
Conclusion: Since the NPV of not going to school is higher, people should disregard schooling. They should work in the entire life period.

Explanation:
- As monopoly is ruled by one set of prices and they are price makers thus even f the prices rise the price will be set above the marginal cost to maximize the profits.

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.
