Question

An auditorium has 100 seats for every 10 rows. Each row has the same number of seats. If s represents the number of seats and r represents the number of rows, which equation represents this proportional relationship?

Answer 1

So we need to find the number of people that can fit in each row. There are 100 seats for every 10 rows. Therefore, there are 10 seats per row. the equation would be:

s/10=r

S is the number of seats. Since 10 is 1/10 of 100, and 100 is s, we would so s/10

Answer 2

The equation s = 10r represents the proportional relationship if an auditorium has 100 seats for every 10 rows option (A) is correct.

What is a proportional relationship?

It is defined as the relationship between two variables when the first variable increases, the second variable also increases according to the constant factor.

The question is incomplete.

The complete question is in the picture, please refer to the attached picture.

We have:

An auditorium has 100 seats for every 10 rows.

s represents the number of seats and r represents the number of rows

Total number of seats = 100

For every 10 rows

s = 10r

Plug r = 10

s = 10(10)

s = 100 seats

Thus, the equation s = 10r represents the proportional relationship if an auditorium has 100 seats for every 10 rows option (A) is correct.
