We have here a case in which we need to translate the verbal phrase into an inequality. In question 4, the case we are solving, we have the word: at least. It means that the other numbers could be larger than 24, but also equal to 24.
Therefore, we can write the inequality as follows:
That is, the sum, 13 + t, is, at least 24, or it could be more than 24 - but also equal to 24.
In summary, we have that the translation into an algebraic expression is given by the next inequality:
