Correct response: 13n+4.5≤38.9, where n is equal to the number.
To solve this problem, we would write the inequality as 13n + 4.5 ≤ 38.9. This inequality represents the sum of 4.5 and one-third of a number being equal to at most 38.9. By solving this inequality, we can find all the possible values of the number that satisfy the given condition.
