Answer:
4.18%
Explanation:
The formula for used for this calculation is given as
Future value = Present( Initial) value (1 + r)ⁿ
Where n = number of years of the investment = 13 years
Future value (Amount of the investment after 13 years)= $5,280
Present ( Initial) value (Amount of the investment before 13 years) = $3,100
r = rate of return
The formula for r is derived as:
r = (Future value/ Present (initial) value)¹/ⁿ- 1
r = ($5,280/$3,100)¹/¹³ - 1
r = 1.0418139573 - 1
r = 0.0418139573
r is always in percentage format
r = 0.0418139573 × 100
r= 4.18139573%
Approximately, the rate of return annually for 13 years = 4.18%

Explanation:
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.
Answer:
Firm A will buy all of the firm B's pollution permits. Each one will cost between $100 and $200.
Explanation:
The firm B will gain from the trade of pollution permits. Firm A will need higher pollution permits since it emits 100 tons of chemicals into air and the cost for eliminating each ton is $200. This cost is higher than the cost to Firm B which is $100 only. Firm A will buy all the pollution permits from Firm B and there will advantage for the Firm B to gain from the trade.
