Calculating the Seating Capacity Before and After Renovation

To calculate the seating capacity before and after the renovation, we need to consider the initial number of rows and seats per row, as well as the changes after the renovation.

- Initially, there were 35 rows with 15 seats in each row. - After the renovation, the number of seats in each row increased by 8, and the number of rows decreased by 3.

Seating Capacity Before Renovation

The initial seating capacity can be calculated as follows: 35 rows * 15 seats = 525 seats

Seating Capacity After Renovation

The seating capacity after the renovation can be calculated as follows: (35 - 3) rows * (15 + 8) seats = 32 rows * 23 seats = 736 seats

Comparison of Seating Capacity

- Before renovation: The waiting room could accommodate 525 passengers. - After renovation: The waiting room could accommodate 736 passengers.

Conclusion

After the renovation, the waiting room could accommodate more passengers, with an increase of 211 seats compared to before the renovation.
