Owners of a recreation area are filling a small pond with water. They are adding water at a rate of 25 liters per minute. There are 600 liters in the pond to start.

Question

Let W

 represent the amount of water in the pond (in liters), and let T

represent the number of minutes that water has been added. Write an equation relating W

 to T

, and then graph your equation using the axes below.

Answer 1

Verbally, we would say the water in the pond is equal to the rate it is added, multiplied by the time that has passed, plus the water that is already in the pond.

as an equation, we would write:

w = 25t +600

in this scenario w would be the y-axis and t is the x-axis.
