To find the value decrease per month, we need to 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 = $4,000 / 12
Calculating this division, we get:
Value decrease per month ≈ $333.33
Therefore, the value decreases by approximately $333.33 per month.
It is recommended that hikers drink 24 ounces of water an hour. If a canteen has 24 ounces of water, how much should the amount of water in the canteen change every 10 minutes?(1 point)

To find the amount of water the canteen should change every 10 minutes, we need to divide the recommended amount of water in an hour by 6 (since there are 6 sets of 10 minutes in an hour).
Recommended amount of water in an hour = 24 ounces
Number of 10 minute intervals in an hour = 60 minutes / 10 minutes = 6 intervals
Amount of water the canteen should change every 10 minutes = Recommended amount of water in an hour / Number of 10 minute intervals in an hour = 24 ounces / 6 intervals
Calculating this division, we get:
Amount of water the canteen should change every 10 minutes = 4 ounces
Therefore, the amount of water in the canteen should change by 4 ounces every 10 minutes.
To find the value decrease per month, we need to divide the total value decrease by the number of months.
Total value decrease: $4,000
Number of months: 12
Value decrease per month = Total value decrease / Number of months
Value decrease per month = $4,000 / 12 = $333.33
Therefore, the value decreases by $333.33 per month.
