The volume of water in a reservoir decreases 21,000 cubic yards over a 3-month period. What is the average change in volume per month?
.
Solution:
To find the average change in volume per month, we need to divide the total decrease in volume by the number of months.
Let x be the average change in volume per month.
Then we have:
21,000 / 3 = x
Simplifying the left side, we get:
7,000 = x
Therefore, the average change in volume per month is 7,000 cubic yards.
To find the average change in volume per month, we need to divide the total change in volume by the number of months.
In this case, the total change in volume is given as 21,000 cubic yards.
The number of months is given as 3.
To find the average change in volume per month, we divide the total change in volume by the number of months:
Average change in volume per month = Total change in volume / Number of months
Average change in volume per month = 21,000 cubic yards / 3 months
Dividing 21,000 by 3, we get:
Average change in volume per month = 7,000 cubic yards
Therefore, the average change in volume per month is 7,000 cubic yards.
To find the average change in volume per month, we can divide the total change in volume over the 3-month period by the number of months.
Step 1: We are given that the volume of water in the reservoir decreases by 21,000 cubic yards over a 3-month period.
Step 2: To find the average change per month, divide the total change in volume (21,000 cubic yards) by the number of months (3).
Average change in volume per month = Total change in volume / Number of months
Average change in volume per month = 21,000 cubic yards / 3 months
Step 3: Perform the division.
Average change in volume per month ≈ 7,000 cubic yards
Therefore, the average change in volume per month is approximately 7,000 cubic yards.
