Owners of a recreation area are filling a small pond with water. They are adding water at a rate of 28 liters per minute. There are 700 liters in the pond to start.

Question

Let W represent the total amount of water in the pond (in liters), and let T represent the total number of minutes that water has been added. Write an equation relating W to T. Then use this equation to find the total amount of water after 13 minutes.

Answer 1

The equation relating W to T is:

W = 28T + 700

To find the total amount of water after 13 minutes, we substitute T = 13 into the equation:

W = 28(13) + 700
W = 364 + 700
W = 1064

Therefore, after 13 minutes, there will be a total of 1064 liters of water in the pond.
