To express the amount of water in the tank after \( t \) minutes, we start with the initial amount of water, which is 300 liters. Since the tank is being drained at a rate of 3 liters per minute, we need to subtract the total amount of water drained over \( t \) minutes from the initial amount.
The amount of water drained after \( t \) minutes is \( 3t \) liters. Therefore, the expression for the amount of water in the tank after \( t \) minutes is:
\[
\text{Amount of water} = 300 - 3t
\]
So, the final expression representing the amount of water in the tank after \( t \) minutes is:
\[
300 - 3t
\]
The amount of water drained after \( t \) minutes is \( 3t \) liters. Therefore, the expression for the amount of water in the tank after \( t \) minutes is:
\[
\text{Amount of water} = 300 - 3t
\]
So, the final expression representing the amount of water in the tank after \( t \) minutes is:
\[
300 - 3t
\]
