The total value of the annuity in 19 years is approximately $10,602.97.
To find the total value of the annuity, we can use the future value formula for an annuity compounded monthly:
![\[ FV = P * ((1 + r)^(nt) - 1)/(r) \]](https://img.qammunity.org/2024/formulas/mathematics/college/q95h37481cqk3swzfavkhs9iso6vxo6qj4.png)
Where:
- FV is the future value of the annuity.
- P is the monthly payment.
- r is the monthly interest rate (expressed as a decimal).
- n is the number of compounding periods per year.
- t is the number of years.
Given:
- P = 104 (monthly payment)
-
(monthly interest rate)
- n = 12 (monthly compounding)
- t = 19 years
Now, plug these values into the formula:
![\[ FV = 104 * ((1 + 0.0566667)^(12 * 19) - 1)/(0.0566667) \]](https://img.qammunity.org/2024/formulas/mathematics/college/rx0kpsfblqhbz4ph3185jo80wntgxhk9ym.png)
Now calculate this expression using a calculator:
![\[ FV \approx 104 * ((1.0566667)^(228) - 1)/(0.0566667) \]](https://img.qammunity.org/2024/formulas/mathematics/college/uex86yl4j22k4fp04efctu85pfkaaj6zvl.png)
![\[ FV \approx 104 * \frac {6.783078 - 1}{0.0566667} \]](https://img.qammunity.org/2024/formulas/mathematics/college/btncfwfgpil9zp7t3d3bn3t113t2fazoru.png)
![\[ FV \approx 104 * (5.783078)/(0.0566667) \]](https://img.qammunity.org/2024/formulas/mathematics/college/9vft1q1744et9jki94s7yqegrr9qoz95rj.png)
![\[ FV \approx 104 * 102.0094 \]](https://img.qammunity.org/2024/formulas/mathematics/college/u2fap5fcw2xlb0874j3hjasthi0mvaiwv5.png)
![\[ FV \approx 10,602.9744 \]](https://img.qammunity.org/2024/formulas/mathematics/college/2y61kdrsnqpt08vreiumjceqplymd2i6ku.png)
So, the total value of the annuity in 19 years is approximately $10,602.97.
