What would you do if you were in the position of the business executives described in the “gift giving and the african elder” ca
lubasha [3.4K]
The business executives were further complicating a situation that was even that complicated to begin with. Tribal elder or not, the business executives were informed that the man was a tribal elder, thus following through with the gift giving customs. This type of act walks hand and hand with the philosophy behind sending something a card. This act should be seen as an act of respect and continued growth, nothing more. This gift should not have been foreseen as an unethical compromise of any <span>kind, but rather a token of appreciation.

Svetradugi [14.3K]

Answer:

Ranking 10% interest rate:

1) 5 years

2) 10 years

3) 1 year

Raking 2% interest rate:

1) 10 years

2) 5 years

3) 1 year

Raking 18% interest rate:

1) 1 year

2) 5 years

3) 10 years

Explanation:

You have to apply to bring the amount of money to present value, according with the information, the formula is the next:

Present Value = Future Value/((1+ interest rate)^(n))

Where n is the number of years that you have to wait to receive the money.

You have to calculate every situation with the respective amount of time and interest rate, the result must be money. and when you get the 9 results, you have to compare every situation and chose the higher amount of money according to the interest rate, for example:

Present value = 140/ ((1+10%)^(1))=  127    

                       =  140/ ((1+10%)^(5))=   149    

                        =  140/ ((1+10%)^(5))=   135

So the answer for the first scenario with an interest rate of 10% is:  

Ranking 10% interest rate:

1) 5 years

2) 10 years

3) 1 year
