Let's assume the number is x.
We are given that the sum of 4.5 and one-third of the number is at most 38.9. Mathematically, we can write this as:
4.5 + (1/3)x ≤ 38.9
To solve this inequality, we can follow these steps:
1. Subtract 4.5 from both sides of the inequality:
(1/3)x ≤ 34.4
2. Multiply both sides of the inequality by 3 to eliminate the fraction:
3 * (1/3)x ≤ 3 * 34.4
x ≤ 103.2
Therefore, all possible values of the number x are less than or equal to 103.2.
