The economy today grows at a rate of 2.2% semiannually. Ayden has an annuity that pays $1,655 at the beginning of every six month period. What is the value of Ayden’s annuity if he receives it in a lump sum now instead of over the next 18 years?

OpenStudy (kidrah69):

PV of the annuity=?

OpenStudy (anonymous):

I don't know.

OpenStudy (kidrah69):

Why not actually try? its obvious

OpenStudy (anonymous):

1,655

OpenStudy (kidrah69):

good PV of the annuity=1,655*(1 - 1.022^-36) in the parentese those are the calculations i did for you for the amount of months. 6 x6=36 then you square it... turn 2.2% in a deciamal

OpenStudy (kidrah69):

*decimal

OpenStudy (anonymous):

0.022

OpenStudy (kidrah69):

PV of the annuity=1,655*(1 - 1.022^-36)/.022 now just solve

OpenStudy (anonymous):

$40,860.16

OpenStudy (kidrah69):

Good :) thats your answer.

OpenStudy (anonymous):

That's not an option. Don't I also need to find the lump sum amount and find the difference?

OpenStudy (kidrah69):

What are your options?

OpenStudy (anonymous):

$47,862.22 $48,978.46 $49,517.22 $50,633.46

OpenStudy (kidrah69):

Do you know how to find the lump sum?

OpenStudy (anonymous):

PV = FV/(1+i)^nt Lump Sum Fromula

OpenStudy (anonymous):

What is FV (Future Value)?

OpenStudy (kidrah69):

yep

OpenStudy (kidrah69):

FV = future value of lump sum PV = future value of lump sum r = interest rate per period t = number of compounding periods

OpenStudy (anonymous):

FV/(1+i)^nt 0.022 * 36 = 0.792 nt = 0.792 i = 0.022 What is FV?

OpenStudy (kidrah69):

Look at what i listed above...

OpenStudy (anonymous):

1,655?

OpenStudy (kidrah69):

iyea

OpenStudy (anonymous):

1,655/(1+0.022)^0.792 = 1626.72 40,860.16 - 1626.72 = 39233.44

OpenStudy (anonymous):

Still not it.

OpenStudy (kidrah69):

hmmm im not sure :/ maybe @ky_lynn might know? i hope :( we have the 1st part right im not sure about the secound part

OpenStudy (anonymous):

@k_lynn

OpenStudy (k_lynn):

I've never heard any of this before. .-.

OpenStudy (kidrah69):

T_T @Smita12 ??

OpenStudy (anonymous):
