Owners of a recreation area are filling a small pond with water. They are adding water at a rate of 26 liters per minute. There are 400 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 11 minutes.

Answer 1

The equation relating W to T can be written as:
W = 26T + 400

To find the total amount of water after 11 minutes, we can substitute T = 11 into the equation:
W = 26(11) + 400
W = 286 + 400
W = 686

So, after 11 minutes, the total amount of water in the pond will be 686 liters.
