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
S = R * 10 By seeing there are 100 seats and 10 rows, we just have to divide 100 by 10. this gives use 10 seats per row. Therefore, the total number of seats (S) is (R) * (10).
