Answer
Explanation:
Step1: Identify the variables
$P = 1500$, $r=0.0625$, $n = 4$ (quarter - ly compounding), $t = 6$
Step2: Use the future - value of an ordinary annuity formula
The formula for the future - value of an ordinary annuity is $A=P\times\frac{(1 + \frac{r}{n})^{nt}-1}{\frac{r}{n}}$. Substitute the values: $\frac{r}{n}=\frac{0.0625}{4}=0.015625$, $nt=4\times6 = 24$. $A = 1500\times\frac{(1 + 0.015625)^{24}-1}{0.015625}$
Step3: Calculate $(1 + 0.015625)^{24}$
$(1 + 0.015625)^{24}\approx1.442973$
Step4: Calculate the numerator
$(1 + 0.015625)^{24}-1\approx1.442973 - 1=0.442973$
Step5: Calculate the value of the annuity
$A = 1500\times\frac{0.442973}{0.015625}=1500\times28.350272\approx42525$
Step6: Calculate the total amount of deposits
The total amount of deposits is $1500\times4\times6=36000$
Step7: Calculate the interest
Interest $=A -$ total deposits. Interest $=42525-36000 = 6525$
Answer:
a. $42525$ b. $6525$
