theu sum of 4.5 abd one-third a number to at most 38.9
Let's represent the number as x.
The expression "one-third a number" can be written as (1/3)x.
The sum of 4.5 and one-third a number is then 4.5 + (1/3)x.
According to the problem, this sum should be at most 38.9. This can be written as:
4.5 + (1/3)x ≤ 38.9
To solve for x, let's isolate the variable on one side:
(1/3)x ≤ 38.9 - 4.5
(1/3)x ≤ 34.4
Now, let's multiply both sides of the inequality by 3 to get rid of the fraction:
3 * (1/3)x ≤ 3 * 34.4
x ≤ 103.2
Therefore, the number x should be at most 103.2 in order for the sum to be at most 38.9.
