Dear uncle,

First of all I would like to thank you for all the attention you have given to my education, it is clear that your financial contribution has helped me a lot to achieve my academic goals, but I am proud to have in my family a person like you, who considers the education an opportunity for life and future change for me and the country.

So I come to bring you news about my college that I am sure will make you happy! In this semester I wrote a scientific article on environmental management that was highly praised by my professors and colleagues, and made me receive an invitation to present at a management and technology congress at a renowned college in the region. This topic is very relevant today and I am happy to be a disseminator of such a relevant subject.

Just as you have given me an opportunity to have a better future through studies, I will endeavor to disseminate relevant information that relates management and environmental sustainability as tools for promoting environmental responsibility in organizations, so that in the future companies will not only be profitable, be instruments that protect the environment and guarantee the quality of life of future generations.

On January 1 of year 1, Arthur and Aretha Franklin purchased a home for $1.5 million by paying $200,000 down and borrowing the r

ASHA 777 [7]

Answer:

a. What is the amount of the interest expense the Franklins may deduct in year 1?

this will depend on the total interest paid during the year, since we are not told how long their mortgage is, we cannot know exactly how much interest expense they will pay. Generally mortgages require monthly payments, so I prepared a simulated amortization schedule for the first year assuming that the mortgage lasts 30 years and a monthly payment of $8,648.93.

year beg. scheduled principal interest ending

balance payment balance

1 1300000 8649 1066 7583 1298934

12 1287931 8649 1136 7513 1286795

total interest $90,582

The total interest that can be deducted in this case would be $90,582 during year 1.

b. Assume that in year 2, the Franklins pay off the entire loan but at the beginning of year 3, they borrow $300,000 secured by the home at a 7 percent rate. They make interest-only payments on the loan during the year. What amount of interest expense may the Franklins deduct in year 3 on this loan (the Franklins do not use the loan proceeds to improve the home)?

$0, interests from home equity loans used for personal expenses are not deductible.

c. Assume the same facts as in (b), except that the Franklins borrow $80,000 secured by their home. What amount of interest expense may the Franklins deduct in year 3 on this loan (the Franklins do not use the loan proceeds to improve the home)?

$0, interests from home equity loans used for personal expenses are not deductible.

Valentin [98]

Answer:

$90,669.85

Explanation:

Present value is the sum of discounted cash flows.

Present value can be calculated using a financial calculator

Cash flow each year year from year one to seven = $10,000

Cash flow for year in year eighth = $10,000 + $80,000 =$90,000

Discount rate = 10%

Present value = $90,669.85

To find the PV using a financial calacutor:

1. Input the cash flow values by pressing the CF button. After inputting the value, press enter and the arrow facing a downward direction.

2. After inputting all the cash flows, press the NPV button, input the value for I, press enter and the arrow facing a downward direction.

3. Press compute
