An individual is now 50 years old, that he plans to retire in 10 years, and that he expects to live for 25 years after he retire
Nutka1998 [239]

Answer:

Ans.  He must save during each of the following 10 years, at the end of each year $32,452.

Explanation:

Hi, in order to find the amount of money that he should have in ten years so he can receive an annual payment of $65,156 for 25 more years (24 payments), we need to bring to present value all 24 payments to year 10. Let me show you the formula.

PresentValue_{10} =\frac{A((1+r)^{n}-1) }{r(1+r)^{n} }

Where:

A= $65,156

n= 24

r= 0.08

Therefore the present value in year 10 is:

PresentValue_{10} =\frac{65,156((1+0.08)^{24}-1) }{0.08(1+0.08)^{24} }=686,012

So that is our present value in year 10, or to put it in other words, our future value (if we look at it from year 0). Now we need to find the annuity (amount to save) that with account for $686,012, plus that $100,000 that he already has saved.

Every should look like this.

686,012=100,000*(1+0.08)^{10} +\frac{A((1+0.08)^{10}-1) }{0.08(1+0.08)^{10} }

And we solve this equation for "A".

686,012=A(14.4865625)+215,892

A=\frac{(686,012-215,892)}{14.4865625} =32,452

Best of luck.

Which statement is true of entrepreneurs?
strojnjashka [21]

Entrepreneurs are people that make their own business. Most businesses tend to have a rough start and can possibly even fail. It depends on how the person creating the business acts and how determined they are to make the business flourish. Although many rich people may of started off of just one product that got advertised well and was sold quickly. Even if it isn't a product but more so a service, you can be very successful. Just know what the people want.

Hope this helped!

suppose you invest $2250 in a CD that earns 3% APR and is compound quarterly. the cd matures in 2 years. how much will this cd b
Oksi-84 [34.3K]

Pn = P0(1+r)∧n

Pnis future value of P0

P0 is original amount invested

r is the rate of interest

n is the number of compounding periods (years, months, etc.)

P(n) = 2250(1+(.03/4)∧8

** since the interest is compounding quarterly, you need to divide the rate by 4, the number of quarters in a year.

Then you would do the math.

GaryK [48]

Answer:

$100,890

Explanation:

To determine the value of the debt we must calculate the present value of the note:

present value = future value of the note / (1 + interest rate)⁵

present value = $170,000 / (1 + 11%)⁵ = $170,000 / 1.11⁵ = $170,000 / 1.685

present value = $100,890
