Transcript text: Find the value of the following ordinary annuity if interest is compounded annually. Find the total amount of interest earned.
\[
\mathrm{R}=\$ 900, \mathrm{i}=0.06, \mathrm{n}=32
\]
The value of the annuity is $\$$ $\square$ . (Round to the nearest cent as needed.)
Solution
Solution Steps
Step 1: Calculate the Future Value of the Annuity
To find the future value \( FV \) of the ordinary annuity, we use the formula:
\[
FV = R \times \frac{(1 + i)^n - 1}{i}
\]
Substituting the given values \( R = 900 \), \( i = 0.06 \), and \( n = 32 \):
\[
FV = 900 \times \frac{(1 + 0.06)^{32} - 1}{0.06}
\]
Step 2: Calculate Total Payments Made
The total payments made over the \( n \) periods can be calculated as:
\[
\text{Total Payments} = R \times n
\]
Substituting the values:
\[
\text{Total Payments} = 900 \times 32
\]
Step 3: Calculate Total Interest Earned
The total interest earned can be found by subtracting the total payments from the future value:
\[
\text{Total Interest} = FV - \text{Total Payments}
\]
Using the values calculated in the previous steps, we find:
\[
\text{Total Interest} = FV - (900 \times 32)
\]
Final Answer
The value of the annuity is \(\boxed{104,195.73}\).
