Answer:
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.
