Question

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?

Answer 1

To find the average change in volume per month, we need to divide the total change in volume by the number of months:

Average change in volume per month = Total change in volume / Number of months

In this case, the total change in volume is 21,000 cubic yards and the number of months is 3. So we have:

Average change in volume per month = 21,000 / 3

Simplifying this expression, 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.

Answer 2

can you do that but as an equation

Answer 3

Sure. Let V be the total change in volume and t be the number of months. Then, we have:

Average change in volume per month = V / t

Substituting V = 21,000 cubic yards and t = 3, we get:

Average change in volume per month = 21,000 / 3

Simplifying this expression, 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.
