And our teacher has a box of 100 markers the teacher gives out silver markers to each student in the class and has 16 markers left over how many students are in the class?

12 students

Step-by-step explanation:

1. 7s+16=100

We know the teacher has 100 markers, and she gave each student 7. If we say that s is the number of students, then 7s is the number of markers she gave out. We also know that she had 16 left over.

2. 7s+16-16=100-16

Subtract 16 from both sides of the equation.

3. 7s=84

Simplify the equation.

4. 7s/7=84/7

Divide both sides by 7.

5. Simplify the equation. Since s is the number of students, we now know how many students there are in the teacher's class.
