To find out how much the car's value decreases per month, you can divide the total decrease in value by the number of months.
Given:
- Total decrease in value = $4,000
- Number of months = 12
Now, perform the division:
\[ \text{Decrease per month} = \frac{-4000}{12} \]
Calculating that:
\[ \text{Decrease per month} = -333.33 \text{ (rounded to the nearest hundredth)} \]
Therefore, the answer is:
−$333.33
