Answer:
$74108
Explanation:
Solution
Given that:
Deposit = $4,500
Interest rate =8.57%
Plan to deposit =$3000 at the end of 5 years through 1
n= 20 years
Now
We apply the formula given below:
A=P(1+r/100)^n
Here
A=future value
P=present value
r=rate of interest
n=time period.
Thus
=4500(1.0857)^20+3000(1.0857)^15+3000(1.0857)^14+3000(1.0857)^13+3000(1.0857)^12+3000(1.0857)^11+3000(1.0857)^10
=$74108
Therefore the account value at 20 years (ending) is $74108
