Answer:
$301605.038
Explanation:
Given :Barney Rubble wishes to withdraw $4000 at the end of every six month period for the next twenty years.
To Find:How much must be deposited now into this account so that he can make these withdrawls?
Assume the account earns 6% compounded semi annually.
Solution:
PMT = Each annuity payment = $4000
n = 2
t = 20
r= 6%= 0.06
Formula:
![FV=PMT[((1+(r)/(n))^(nt) -1)/((r)/(n))]](https://img.qammunity.org/2020/formulas/mathematics/college/rwd51x3hpcfwgbd67rgy5214vovckmntwy.png)
![FV=4000[((1+(0.06)/(2))^(2 * 20) -1)/((0.06)/(2))]](https://img.qammunity.org/2020/formulas/mathematics/college/90g4u1tcymzv7lalap2ofr9hij473smls7.png)

Hence He must deposit $301605.038 into this account so that he can make these withdrawals
