A: the letter C stands for the number of chair with students sitting with them. Write an equation that will help you find c?

Answer 1

3 tables of 3rd graders times 4 chairs per table = 3*4 chairs or 12 chairs.
6 tables of 4th graders times 4 chairs per table = 6*4 chairs or 24 chairs.

3*4 + 6*4 = c
12 + 24 = c
36 = c

Answer 2

23-3-6=14 students
yeah did is my answer
