To determine how long the dehumidifier can run before it becomes full, we can let \( h \) represent the time in hours. Since the dehumidifier removes 2 quarts of water per hour, after \( h \) hours, it will have removed \( 2h \) quarts.
The dehumidifier can hold up to 50 quarts before it becomes full, which gives us the inequality:
\[ 2h \leq 50 \]
Thus, the correct inequality representing how much time the dehumidifier can run before it becomes full is:
2h ≤ 50
