To find the value decrease per month, we can divide the total decrease by the number of months.
Total decrease = $4,000
Number of months = 12
Value decrease per month = Total decrease / Number of months
Value decrease per month = $4,000 / 12
Using division, we find that the value decrease per month is approximately $333.33, which is closest to the first response: $333.33.

To find the amount of water that should be consumed every 10 minutes, we can divide the total amount of water consumed in an hour (24 ounces) by the number of 10-minute intervals in an hour (6 intervals).
Total amount of water consumed in an hour = 24 ounces
Number of 10-minute intervals in an hour = 60 minutes / 10 minutes = 6 intervals
Amount of water consumed every 10 minutes = Total amount of water consumed in an hour / Number of 10-minute intervals
Amount of water consumed every 10 minutes = 24 ounces / 6 intervals
Using division, we find that the amount of water that should be consumed every 10 minutes is 4 ounces, which is closest to the fourth response: 4 ounces.
To solve this problem using division of rational numbers, we divide the total decrease in value ($4,000) by the number of months (12).
$4,000 / 12 = $333.33
Therefore, the value of the car decreases by approximately $333.33 per month.
To find the value that the car decreases per month, we need to divide the total decrease in value by the number of months. In this case, the car's value decreases by $4,000 in the first 12 months.
To calculate the decrease per month, we can use the following formula:
Decrease per month = Total decrease / Number of months
Using the values given, we have:
Decrease per month = $4,000 / 12
Calculating this division, we get:
Decrease per month ≈ $333.33
Therefore, the correct answer is $333.33.
