Answer:
B. The total interest = $4.35
Explanation:
The first question to answer, is what is the present value of the annuity of the loan and then based on that the total interest can be calculated.
<h2>Present value of annuity= A x [(1-(1+r)-n)/r]*(1+r) </h2>
Where the A represents Annuity = or $20
The r represents the rate or 1.5%
and the n represents the number of periods which is 6 months
Calculating the value =
= 20 x [(1-1.015^-6)/0.015]*1.015
= 20 x [(1-0.91454219251)/0.015]*1.015
= 20*5.782644973
=$115.65
Now that the loan amount is known, the Total Interest can be calculated as follows
Total Interest= number of payments x monthly payments) - the loan amount (calculated above)
= 20 x 6 -115.65
= 120-115.65
The total interest = $4.35
Answer:
9.68%
Explanation:
Percent Return on Investment is calculated as Net Profit / Cost of Investment x 100
Net Profit= $46,620 (1,000 x $46.62 per share) + $950 (1,000 x $.95 per share) - $43,370 (1,000 x $43.37 per share) = $4,200
Cost of Investment= $43,370 (1,000 x $43.37 per share)
Percent Return on Investment= $4,200 / $43,370 x 100 = 9.68%
Answer:
D) The supply of the output from the hydroelectric power plants to increase
Explanation:
The externality here is a negative one where the hydroelectric plants has to bear the cost of pollution as the paper mills operates.
Correcting means to make the paper mills pay for the external costs of their production and compensate the power plant for the additional cost that incurred as they have to clean up the water.
As the cost of production reduces, the power plant will be more willing to supply electricity at similar prices, ie. their supply curve will shift to the right. It will intersect with the demand curve of the consumers at a point with higher quantity (and maybe lower price)
In other words, they will supply more electricity.
