going for every 9 students going.
Answer: So, 72 students are going to the concert.
34. 4-3 Problem-Solving Strategy: Make a Table
Check
Divide the total number of teachers by the
number of teachers per group.
16 Ă· 2 = 8
There are 8 groups going. There are 9 students
in each group. So, there are 8 x 9 = 72 students
going altogether. The answer is correct.
