The possible number of rows in the auditorium can be 9, 10, 11, 12, 13, 14, 15, 16, 17, or 18
<h3><em><u>Solution:</u></em></h3>Given that auditorium has rows of seat 8 seats in each row
1 row = 8 seats
Kayla knows there are at least 70 seats but fewer than 150 seats in the auditorium
Let the number of seats be x
Therefore,
70 < x < 150
We know that 1 row has 8 seats
First number after 70 which is divisible by 8 is 72
Since 8 is the number of seats in each row so, 9 denotes the number of rows
Last number just before 150 which is divisible by 8
Since 8 is the number of seats in each row so, 18 denotes the number of rows
So, the actual number of rows can be between 9 and 18
We can say that possible number of rows can be 9, 10, 11, 12, 13, 14, 15, 16, 17, or 18
