Answer:
$1,194.05
Explanation:
The applicable formula is A = P x ( 1+ r) ^ n
Where A is the future amount
P is principal amount $1000
r is 6% per year or 0.06
n= time in years; 3 years
Since interest is compounded semi-annually, r will be 0.06 /2 = 0.03
n will be 3 years /2 = 6 periods
A = $1000 x ( 1 + 0.03) ^ 6
A = $1000 x 1.194052
A=$1,194.05
Suppose $250,000 is used to establish an annuity that earns 6%, compounded quarterly, and pays $6000 at the end of each quarter. It will take about 120 quarters until the account balance reaches $0.
Amount invested (Present value) = $250000
Quarterly payment (At the end of each quarter) (P) = $4500
Interest Rate (Quarterly) (r) = 6% /4
= 1.5% = 0.015
A number of quarters (n) = ?
Future value at the end = 0
Present value of Annuity formula:
Present value = P × 
250000 = 4500 × 
250000 = 300000 × 
250000 / 300000 = 
0.83333 = 
n = 120
Hence is shall take 120 Quarters until the account balance is $0.
