The inequality that represents the given situation is 18 + 4t > 54.
To solve for t, we can subtract 18 from both sides of the inequality:
4t > 36.
Finally, we can divide both sides of the inequality by 4 to solve for t:
t > 9.
Therefore, the possible numbers of minutes Mai could add water are t > 9.
