Answer:
Between 9 and 20rows; at least of 9 rows
Step-by-step explanation:
Since there are eight seats in a row and in the auditorium we have about 70 to 150seats, the number of rows of seats that can fit into the auditorium will be between 70/8 and 150/8 rows which is equivalent to 8.75 and 19.75 rows in the auditorium. This is approximately 9 to 20 rows.
This shows that about 9 to 20 rows can fit into the auditorium.
The least possible number of rows means the lowest number of rows we can have in the auditorium which is 9rows according to the calculation above
