To model the amount of water remaining in the tank, we consider the initial amount of water and the rate at which it is being drained.

Given:

The tank starts with 100 liters of water.

Water is drained at a rate of 5 liters per minute.

Let t represent the number of minutes the water has been draining.

Let W(t) represent the amount of water remaining.

Initially, the tank contains 100 liters of water. Water is being drained at a rate of 5 liters per minute. The total amount of water that has been drained from the tank after t minutes is 5t. Thus, the amount of water left after t minutes is the initial am...
