$$  $$$$ 500\left\lbrack\frac{\left(1+0.00875\right)^{43}-1)}{0.00875}\right. $$$$ \rbrack $$$$ \rbrack $$

To solve the expression $ 500\left[\frac{\left(1+0.00875\right)^{43}-1}{0.00875}\right] $, we will follow these steps:

1. **Calculate the base**: $ 1 + 0.00875 = 1.00875 $.

2. **Raise the base to the power of 43**:
   \[
   (1.00875)^{43}
   \]

3. **Subtract 1 from the result**:
   \[
   (1.00875)^{43} - 1
   \]

4. **Divide the result by 0.00875**:
   \[
   \frac{(1.00875)^{43} - 1}{0.00875}
   \]

5. **Multiply by 500**:
   \[
   500 \times \left[\frac{(1.00875)^{43} - 1}{0.00875}\right]
   \]

Now, let's compute each step.

### Step-by-Step Calculation:

1. **Base**: $ 1.00875 $
2. **Power**: $ (1.00875)^{43} \approx 1.468085 $
3. **Subtract 1**: $ 1.468085 - 1 = 0.468085 $
4. **Divide**: $ \frac{0.468085}{0.00875} \approx 53.495429 $
5. **Multiply by 500**: $ 500 \times 53.495429 \approx 26747.7145 $

So, the final result is approximately **26,747.71**.
