1. The problem asks for the monthly tax due on an amount of 39000. 2. To solve this, we need the tax rate or formula, which is not provided in the question. Assuming the tax due is calculated as a percentage of 39000, we denote the tax rate as $r$. 3. The formula for tax due is: $$\text{Tax Due} = 39000 \times r$$ 4. Without the tax rate $r$, we cannot calculate the exact tax due. The options given are 2423.4, 2425.4, 2426.4, and 2427.4. 5. To find $r$, we can check which option corresponds to a reasonable tax rate: For example, if tax due is 2425.4, then $$r = \frac{2425.4}{39000} \approx 0.0622 = 6.22\%$$ 6. Similarly, for 2423.4: $$r = \frac{2423.4}{39000} \approx 0.0621 = 6.21\%$$ 7. The difference between options is small, so the tax rate is approximately 6.2%. 8. Without additional information, the best we can do is identify the tax due as approximately 2425.4, assuming a 6.22% tax rate. Final answer: 2425.4
