Write an expression to represent the number of liters in Tank B after t minutes, where t represents the number of minutes.

Question

Tank A
starts with 400 liters
leaking 3 liters per minute

400+(−3t)
Tank B
starts with 180 liters
filling 5 liters per minute

Answer 1

To represent the number of liters in Tank B after \( t \) minutes, you can start with the initial amount of water in Tank B and add the amount of water being filled over time.

Tank B starts with 180 liters and is filling at the rate of 5 liters per minute. Therefore, the expression for the volume of water in Tank B after \( t \) minutes is:

\[ 180 + 5t \]

In summary:

• Initial amount: 180 liters
• Filling rate: 5 liters per minute
• Expression for Tank B: \( 180 + 5t \) liters after \( t \) minutes.
