Suppose the lake by your house as 198,000 gallons. But its volume grew by 3000 every weekWrite an equation modeling the number of gals in the lake after so many weeks

Sagot :

Given:

The current volume of the lake is 198,000 gallons.

Its volume grew by 3000 gallons every week

To find: An equation modeling the number of gallons in the lake after some weeks.

Explanation:

As we know,

If the growth or decay involves increasing or decreasing by a fixed number, then we must use a linear function.

Here, the increasing rate is 3000.

The current volume is 198,000 gallons.

Thus, the linear function that represents this situation is,

[tex]V=3000w+198000[/tex]

Where w represents the number of weeks and V represents the volume.

Final answer:

The equation is,

[tex]V=3000w+198000[/tex]
