Answer 2

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

`9 * 8 = 72`

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

`18 * 8 = 144`

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
