Answer:
Approximately 16 rows will be required so that everyone has a seat.
Step-by-step explanation:
We are given the following in the question:
Total number of students = 250
Number of seats in each row = 16
Total number of rows required for everyone to sit =
[tex]=\dfrac{\text{Total number of student and teachers}}{\text{Number of seats in each row}}\\\\=\dfrac{250}{16}\\\\=15.625\\\approx 16[/tex]
Thus, approximately 16 rows will be required so that everyone has a seat.
Some seats will be left unused in the last row.
Number of seats unused =
[tex](16)(16) - 250 = 6[/tex]
6 seats are left unused.
