Answer:
Given :An auditorium has rows of seats with 8 seats in each row. kayla knows there are at least 70 seats but fewer than 150 seats in the auditorium.
To Find : How many rows of seats can be there be in the auditorium?
Solution :
No. of seats in a row = 8
Now we are given that There are at least 70 seats but fewer than 150 seats
Let the number of seats be x
So, 70<x<150
First number after 70 which is divisible by 8 is 72
[tex]9 \times 8 = 72[/tex]
Since 8 is the number of seats in each row so, 9 denotes the no. of rows
Last number just before 150 which is divisible by 8
[tex]18 \times 8 = 144[/tex]
Since 8 is the number of seats in each row so, 18 denotes the no. of rows
Hence the number of rows can be from 9 to 18 i.e. 9,10,11,12,13,14,15,16,17,18
