Answer
Explanation:
Step1: Identify the formula
We use the future - value of an ordinary annuity formula $FVA = A\times\frac{(1 + r)^{n}-1}{r}$, where $A$ is the annual payment, $r$ is the interest rate per period, and $n$ is the number of periods. Here, $A=$15000$, $r = 0.08$, and $n = 30$.
Step2: Calculate $(1 + r)^{n}$
$(1 + 0.08)^{30}=10.06265689$.
Step3: Calculate $(1 + r)^{n}-1$
$10.06265689-1 = 9.06265689$.
Step4: Calculate $\frac{(1 + r)^{n}-1}{r}$
$\frac{9.06265689}{0.08}=113.2832111$.
Step5: Calculate $FVA$
$FVA=15000\times113.2832111 = 1699248.167$.
Answer:
$1699248$
