From the given table,
1 Pizza corresponds to 4 students
2 Pizza corresponds to 8 students
3 Pizza corresponds to 12 students
4 Pizza corresponds to 16 students
As you notice, for every pizza there are 4 students,
so the multiplier is 4.
2 pizza x 4 = 8 students
3 pizza x 4 = 12 students
4 pizza x 4 = 16 students
The answer is Option B. Multiply the number of pizza by 4 to find the number of students
