To find the number of rows that are empty, we need to figure out how many full rows have been filled with seats and then subtract that from the total number of rows in the auditorium.
First, let's calculate how many full rows have been filled with seats. We know that there are 7 seats in each row and 70 people seated. So, we can divide the total number of people seated by the number of seats per row to get the number of full rows.
70 people seated รท 7 seats per row = 10 full rows
Now, we can subtract the number of full rows from the total number of rows in the auditorium to find the number of empty rows.
Total rows - Full rows = Empty rows
168 rows - 10 full rows = 158 empty rows
Therefore, there are 158 rows that are empty.
168 / 7 = total rows
70 / 7 = occupied rows
