To find the number of liters of water in the tank after 20 minutes, substitute \( t = 20 \) into the expression \( 300 + (-3t) \).
\[
300 + (-3(20))
\]
Calculate \( -3(20) \):
\[
-3(20) = -60
\]
Now substitute this back into the expression:
\[
300 - 60 = 240
\]
After 20 minutes, there will be **240 liters** of water in the tank.
\[
300 + (-3(20))
