Answer:
4284 persons
Explanation:
The new population of the town will be computed as:
Increase in population = Current population × Increase in population %
where
Current population is 4200 persons
Increase in population % is 2%
Putting the values above:
= 4200 persons × 2%
= 84 persons
So, the new population would be:
New population = Current population + Increase in population
= 4200 + 84 persons
= 4284 persons
Therefore, next year, there would be 4284 persons
Answer:
<u>13.2%</u>
Explanation:
As per Capital Asset Pricing Model (CAPM),
Expected Rate Of Return = 
wherein,
= Risk free rate of return on treasury bonds
B= Beta , which represents the degree of sensitivity of security return to the market return.
= Return on market portfolio
Thus, Expected rate of return of security X = 6 + 1.2(12 - 6)
= 13.2%
CAPM model is used for calculating expected rate of return. As per the model, the investors expect a risk premium represented by excess of rate of return of market portfolio over risk free rate , in addition for the risk free rate of return.
The risk premium serves as a compensation for investing in risky securities instead of risk free securities.
Answer:
A) Marginal private cost= 50
B) Total Marginal social cost to society = 70
Explanation:
A) In order to find the marginal private cost we will use the firms production cost formula as it is the private cost that the firm is enduring and is only relevant to the firm's cost and not the society's cost.
In order to find the marginal unit cost of the 10th unit produced will will replace Q in the formula by 10 as it represents quantity.
MC= 10 + 4Q
MC= 10 + 4(10)
MC= 10 +40 = 50
B) In order to find the marginal cost to society we will add the marginal external cost of the 10th unit to its private cost. We already know the marginal private cost is 50 now we need to find the marginal external cost to it to find the total marginal cost.
Marginal external cost = 2Q
Q= 10
Marginal external cost = 2*10 =20
The total Marginal cost to society= 50 + 20= 70
I think the most appropriate answer would be D. As other answers has nothing to do with this question.
I hope it helped you!
