Question

An auditorium has rows of seats with a seats in each row Kayla

Answer 1

Step-by-step explanation:

• Note: there is a typo, 'a' should be '8'

The number of seats in each row is 8 and the total number of seats is between 70 and 150.

Let x be the number of rows, then we have the inequality:

• 70 ≤ 8x < 156

Divide all sides by 8 to get:

• 70/8 ≤ x < 156/8
• 9 ≤ x ≤ 19 (taking closest integers)

So the number of rows is between 9 and 19 both inclusive.

All possible number of rows

• 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19
