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

100 divide 10 there must be 10 rows im guessing?

Answer 2

`s=10r`

Step-by-step explanation:

Having that the number of seats is constant for every row (making the relationship proportional between the two variables), you can use the rule of three:

10 Rows for 100 Seats

1 Row for ? Seats

`s = (100/10) r = 10r`
