Answer:
To calculate the future value of a 5-year ordinary annuity with annual payments of $1,585 at a 12.28% interest rate, you can use the future value of an ordinary annuity formula:
=
×
(
1
+
)
−
1
FV=P×
r
(1+r)
n
−1
where:
P is the annual payment ($1,585)
r is the annual interest rate (12.28% or 0.1228)
n is the number of periods (5 years)
Plugging in the values:

1.78737−1=0.78737
Then, divide by
r:

≈
6.412
0.1228
0.78737
≈6.412
Finally, multiply by the annual payment:

FV=1585×6.412≈10,159.22
So, the future value of the annuity is approximately
