Problema Solution

You are considering investing in a security that will pay you ​$4000in 29 years.

a.  If the appropriate discount rate is 11percent​, what is the present value of this​ investment?

b.  Assume these investments sell for ​$746 in return for which you receive ​$400 in 29 years. What is the rate of return investors earn on this investment if they buy it for ​$746

Answer provided by our tutors

I = $4,000

t = 29 years

r = 11% or 0.11

We are assuming that the interest is simple.

a.

P = the present value

I = P*r*t

4,000 = P*0.11*29

P*0.11*29 = 4000

P = $1,253.92

The present value of the investment is  $1,253.92.

b.

P = $746

I = $400

t = 19 years

r = the rate of return as decimal

I = P*r*t

746*r*29 = 400
