Answer:

hello your question lacks the required file ( excel file ) attached below is the missing file

Answer : The EVI does not change in the way expected and this is because of the higher probability assignment

Explanation:

1) calculate the EVI for the first combination

i.e. B5 = $2000, B9 = 0.4, B14 = 0.8, B15 = 0.3

EVI = EMI with information - EMI without information

= 3250 - 3400

= $ 150

<em>note : EMI with information is gotten via solution tree </em>

2) Calculate the EVI for the second combination

i.e. B5 = $4000 , B9 = 0.3 , B14 = 0.9, B15 = 0.2

EVI = EMI with information - EMI without information

= $1378 - $500 = $878

You are scheduled to receive annual payments of $60,000 for each of the next 20 years. The annual rate of return is 8 percent. W

babymother [125]

Answer:

= $ 219,657.43

Explanation:

FV of annuity = P x [(1+r) n -1/r]

P = Periodic payment = $ 20,000

r = Periodic interest rate = 0.08

n = Number of periods = 20

FV = $ 60,000 x [(1+ 0.08)20 -1/0.08]

= $ 60,000 x [(1.08)20 -1/0.08]

= $ 60,000 x [(4.66095714384931 -1)/0.08]

= $ 60,000 x (3.66095714384931/0.08)

= $ 60,000 x 45.7619642981163

= $ 2,745,717.85788698 or $ 2,745,717.86

FV of annuity due =(1+r) x P x [(1+r) n -1/r]

= (1+0.08) x $ 2,745,717.85788698

= 1.08 x $ 2,745,717.85788698

= $ 2,965,375.28651794 or $ 2,965,375.29

Difference in FV of ordinary annuity and annuity due

= $ 2,965,375.29 - $ 2,745,717.86

= $ 219,657.43
