Jackie is setting up chairs in the gymnasium for a magic show. She needs to have seats for 78 students and 3 teachers. She has to have 12 chairs in a row. How many rows will there be? How many seats will be empty?
​
a.
6 rows and 9 people will stand
b.
10 rows and no seats will be empty
c.
7 rows and 3 seats will be empty
d.
7 rows and 13 seats will be empty

Answer :

C is your answer because 78+3 is 81 12x7 is 84 so you will have 3 seats left
First, you need to do 78+3 to get 81.

That is how many people are there.

Now you have to divide 81 by 12.

You will get 6.75

This means that your answer will be C because there needs to be 7 rows, and 3 chairs will be left over!


Hope this helps!
