To find out how much the value of the car decreases per month, we divide the total decrease in value by the number of months.
Total decrease in value = -$4,000
Number of months = 12
Now, we can perform the division:
\[ \text{Monthly decrease} = \frac{-4000}{12} = -333.33 \]
Thus, the value of the car decreases by approximately \(-$333.33\) each month when rounded to the nearest hundredth.
So the correct response is:
−$333.33
