Question

An event planner expects 432 teachers to attend a conference. If the planner places 24 chairs in each row, estimate the number of rows needed to provide seating for all of the teachers.

Answer 1

The number of rows needed to provide seating for all teachers is 18.

Explanation:

Here, the total number of guests expected to attend = 432 teachers

Now, given : The number of chairs placed in each row = 24

Let us assume , the total number of rows of chairs = m

Now, The total chairs in the conference room

= The number of rows x The chairs in each row

= 24 x (m) = 24 m

Also, the TOTAL CHAIRS = TOTAL GUEST EXPECTED

⇒ 24 m = 432

or, m = 432 / 24 = 18

or, m = 18

Hence, the number of rows needed to provide seating for all of the teachers is 18.
