Answer 2

To find the monthly decrease in the car's value, you divide the total decrease in value by the number of months.

The car's value decreases by $4000 over 12 months:

\[
\text{Monthly Decrease} = \frac{\text{Total Decrease}}{\text{Number of Months}} = \frac{4000}{12} \approx 333.33
\]

This means the car’s value decreases by approximately $333.33 per month.

To express this as a rational number:
- \( -\frac{4000}{12} = -\frac{1000}{3} \) which is approximately \(-333.33\).

Thus, the correct response is:

**−$333.33**.
