To solve the problem, we start with the inequality described: the sum of 4.6 and one-third of a number \( n \) is equal to at most 39.1. We can express this as:
\[ 4.6 + \frac{1}{3}n \leq 39.1 \]
Next, we need to isolate \( n \). Let's subtract 4.6 from both sides:
\[ \frac{1}{3}n \leq 39.1 - 4.6 \]
Calculating the right-hand side:
\[ 39.1 - 4.6 = 34.5 \]
Now our inequality is:
\[ \frac{1}{3}n \leq 34.5 \]
To eliminate the fraction, we multiply both sides by 3:
\[ n \leq 34.5 \times 3 \]
Calculating the multiplication:
\[ 34.5 \times 3 = 103.5 \]
Thus, we have:
\[ n \leq 103.5 \]
This means that the possible values of the number \( n \) are all values that are less than or equal to 103.5. Therefore, the correct option is:
n ≤ 103.5
n less than or equal to 103.5
