a) Correct Answer : 11778.46
Present Value of annuity is given by the formula,
PV = P [{ 1 - (1+r) -n } / r]
Where,
· Perodic Period
· Rate per period
· n = number of periods
Now substituting the values,
· Here P = $ 45,000
· r = 0.05
· n= 30
The present value of annuity = 45,000 [ { 1 - (1+0.05) -30 } / 0.05]
= 45,000[ { 1 - (1.05) -30 } / 0.05]
= 45,000[ (1 - 0.2314) / 0.05]
= 45,000 [ (0.7686) / 0.05]
= 45,000 X 15.3725
= $ 691760.296
Thus ,you need $ 691760.296 in your account at the beginning.
Part b)
Total money will you pull out of the account = Period withdrawals X Amount of withdrawals
Therefore, Total money will you pull out of the account = 30 X 45,000 = $ 1350000
Part c ) Money in the form of interest = Total money pull out - amount deposited in the beginning
Therefore, Total Interest = 1350000 - 691760.296 = $ 658239.704
