Transcript text: Maria invests $\$ 8,000$ in a ban Maria's account balance at th $\$ 9,504.80$ $\$ 9,440.00$ $\$ 8,720.00$ $\$ 8,018.00$

Solution

Solution Steps

Step 1: Identify the Investment Parameters

Maria invests $ P = 8000 $ dollars. To calculate the account balance at the end of the investment period, we need the interest rate $ r $ and the time period $ t $. Since these values are not provided, we cannot compute the exact balance.

Step 2: Formulate the Balance Calculation

If we had the interest rate and time, the balance could be calculated using either simple interest or compound interest formulas:

For simple interest: \[ A = P(1 + rt) \]
For compound interest: \[ A = P \left(1 + \frac{r}{n}\right)^{nt} \] where $ n $ is the number of times interest is compounded per year.

Step 3: Conclusion

Without the values for $ r $ and $ t $, we cannot determine the final account balance. Therefore, we cannot select an answer from the provided options.
