Janelle is in charge of bringing in dry erase markers for everyone in her math group to use to work on a project. She brings 3 markers for each person in her group and 5 extra markers for everyone to share. If Janelle brings in 23 markers in all, which equation represents the information?

Question

Let x represent the number of students in Janelle’s group.
3x = 23 + 5
3x = 23
3x – 5 = 23
3x + 5 = 23

Answer 1

To solve the problem, we need to set up an equation based on the information provided. Janelle brings 3 markers for each person in her group (which is represented by \(x\), the number of students), and she also brings in 5 extra markers. The total number of markers she brings is 23.

The equation that represents this situation is:

\[ 3x + 5 = 23 \]

This is because \(3x\) accounts for the 3 markers per student multiplied by the number of students \(x\), and the \(5\) accounts for the extra markers she brings in. So the correct choice is:

3x + 5 = 23
