The sum of 4.6 and one-third of a number is at most 39.1. What are all the possible values of the number?

Artem wrote the inequality [tex]\frac{1}{3}n + 4.6 \leq 39.1[/tex], where [tex]n[/tex] represents the number, to help solve this problem.

Solve his inequality:

A. [tex]n \leq 112.7[/tex]
B. [tex]n \leq 131.1[/tex]
C. [tex]n \leq 103.5[/tex]
D. [tex]n \leq 11.5[/tex]

Answer :

To solve the inequality Artem wrote, which is [tex]\(\frac{1}{3} n + 4.6 \leq 39.1\)[/tex], we will follow these steps:

1. Subtract 4.6 from both sides of the inequality to isolate the term with [tex]\(n\)[/tex]:

[tex]\[
\frac{1}{3} n + 4.6 - 4.6 \leq 39.1 - 4.6
\][/tex]

Simplifying the right side will give us:

[tex]\[
\frac{1}{3} n \leq 34.5
\][/tex]

2. Multiply each side of the inequality by 3 to solve for [tex]\(n\)[/tex]:

[tex]\[
3 \times \frac{1}{3} n \leq 34.5 \times 3
\][/tex]

This simplifies to:

[tex]\[
n \leq 103.5
\][/tex]

Therefore, the possible values of the number [tex]\(n\)[/tex] are such that [tex]\(n\)[/tex] is less than or equal to 103.5. The correct answer is [tex]\(n \leq 103.5\)[/tex].
