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:
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.
In a project network, the critical path is the sequence of activities which has the longest time. A series of interconnected tasks known as the critical route has a direct impact on the project's completion date.
<h3>What do you men by the project network?</h3>
A project network is a graph that displays the actions, lengths of time, and dependencies among your project's tasks.
Techniques like Gantt charts, PERT charts, and critical path management can be used to form project networks. The project network has a number of paths, but each terminal piece must be located on just one of those paths.
A project's workflow is shown graphically in a project network diagram. A network diagram is a project management chart that lists boxes for activities and roles, followed by arrows that show the timetable and order in which the work must be done.
Therefore, in a project network, the critical path is the sequence of activities which has the longest time. A series of interconnected tasks known as the critical route has a direct impact on the project's completion date.
