Answer:
a. $800
b. $1,000
Explanation:
In this case, the opportunity cost of holding the money instead of buying a U.S. Treasury bond is determined as the yearly interest payed by the bond.
a. interest rate = 8%
The opportunity cost of keeping the $10,000 is:

b. interest rate = 10%
The opportunity cost of keeping the $10,000 is:

Compounding interest is interest on top of interest.
For example, say you put 100 bucks in the bank.
You get 10% interest compounded daily on that 100 bucks.
That means that you get 10% interest not only on those 100 bucks, but all the money you make after.
So your interest would go from 10% on 100 bucks, to 10% on 110 bucks and so forth.

Answer:
The correct answer is c) rises.
Explanation:
Each country in question will specialize in what is most efficient. At the same time, it will import the rest of the products in which they are most ineffective in terms of production. Although a country does not have an absolute advantage in producing any good, it may specialize in those goods in which it finds a greater comparative advantage and finally participate in the international market. In this sense, it can boost its foreign trade.
It is then the basic idea that countries choose to specialize in order to trade in activities where they have a certain advantage. That is, instead of producing what they do best in an absolute way, they produce what they do best in a relative way. Therefore, the difference with the theory of absolute advantage is that it does not produce what the country costs less, but the one with lower comparative costs.
Answer:
The correct answer is $83230
Explanation:
Solution
Given that:
The Present worth of geometric series is shown below
= A *[1 - (1+g)^n /(1+i)^n] / (i-g)
Now,
The present cost of worth from EOY 5 to EOY 13 at EOY 4 = 7000 *[1 - (1+0.12)^9 /(1+0.15)^9] / (0.15-0.12)
Thus,
= 7000 *[1 - (1.12)^9 /(1.15)^9] / (0.03)
Which is,
= 7000 * 7.0572647
= 49400.85
Now, The NPW of all costs = 35000 + 7000*(P/A,15%,4) + 49400.85*(P/F,15%,4)
= 35000 + 7000*2.854978 + 49400.85*0.571753
= 83229.93
Therefore the sound improvement better result in a net present worth profit of how much to negate the costs is $83229.93 or 83230
Note: EOY = End of year.
