The sum of 4.6 and one-third of a number is equal to at most [tex]$39.1$[/tex]. 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] is the number. Solve his inequality.

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

Answer :

Sure, let’s solve the inequality step-by-step!

1. Start with the inequality:
[tex]\(\frac{1}{3} n + 4.6 \leq 39.1\)[/tex]

2. Isolate the term with [tex]\(n\)[/tex]:
Subtract 4.6 from both sides to move it to the right side of the inequality:
[tex]\[
\frac{1}{3} n \leq 39.1 - 4.6
\][/tex]
Simplifying the right side gives:
[tex]\[
\frac{1}{3} n \leq 34.5
\][/tex]

3. Solve for [tex]\(n\)[/tex]:
To eliminate the fraction, multiply both sides by 3.
[tex]\[
n \leq 34.5 \times 3
\][/tex]
Simplifying the multiplication, we get:
[tex]\[
n \leq 103.5
\][/tex]

Therefore, the possible values for the number [tex]\(n\)[/tex] are all numbers less than or equal to 103.5. The correct choice is [tex]\(n \leq 103.5\)[/tex].
