Step-by-step explanation:
The formula to find the compound amount after t years (compounded semiannually) :-
![A=P(1+(r)/(2))^(2t)](https://img.qammunity.org/2020/formulas/business/high-school/h8wp34kqdr74ww4c95s3phu88eomvftk30.png)
Given : Principal amount : P = $ 8,000
Rate of interest :
![r=0.05](https://img.qammunity.org/2020/formulas/business/high-school/1c9t8sixu2bcmxd8ovxk5zmbx52bum096f.png)
Time : 9 years
Now,
![A=8000(1+(0.05)/(2))^(2*9)](https://img.qammunity.org/2020/formulas/business/high-school/6xvhrmvqote7q8qntuaj2zudpypwwjgf4u.png)
![A=8000(1+0.025)^(18)=12477.2697417\approx\$12477.27](https://img.qammunity.org/2020/formulas/business/high-school/dgtk3krh3g85oh234zwfh9tnn5j9spl6xu.png)
The final amount in the account will be $12477.27
