Calculation of Remaining Tickets for the Evening Session

To calculate the number of tickets remaining for the evening session, we need to subtract the number of tickets sold before and after lunch from the total number of seats in the theater.

Given: - Small theater hall with 20 rows and 15 seats in each row. - 85 tickets were sold before lunch. - 120 tickets were sold after lunch.

To calculate the total number of seats in the theater, we multiply the number of rows by the number of seats in each row: 20 rows * 15 seats = 300 seats.

To calculate the number of tickets sold, we add the number of tickets sold before lunch and after lunch: 85 tickets + 120 tickets = 205 tickets.

To calculate the number of tickets remaining, we subtract the number of tickets sold from the total number of seats: 300 seats - 205 tickets = 95 tickets.

Therefore, there are 95 tickets remaining for the evening session.
