To calculate the future value of an investment compounded annually, you can use the formula:
\[
A = P(1 + r)^t
\]
where:
- \( A \) is the amount of money accumulated after n years, including interest.
- \( P \) is the principal amount (the initial amount of money).
- \( r \) is the annual interest rate (decimal).
- \( t \) is the number of years the money is invested or borrowed.
In this case:
- \( P = 4900 \)
- \( r = 8.75\% = 0.0875 \)
- \( t = 12 \)
Now plug the values into the formula:
\[
A = 4900(1 + 0.0875)^{12}
\]
Calculating \( 1 + 0.0875 \):
\[
1 + 0.0875 = 1.0875
\]
Now calculate \( (1.0875)^{12} \):
\[
(1.0875)^{12} \approx 2.2952
\]
Now calculate \( A \):
\[
A \approx 4900 \times 2.2952 \approx 11247.48
\]
Rounding to the nearest dollar, the investment will be worth approximately:
\[
\boxed{11247}
\]
