Here is the full question

There are 17 rows of seats in a cinema. There are 22 seats in each row. A film was shown in the cinema on friday night. Each ticket for the film cost £7.50

The sale of tickets for that night made £2587.50

How many tickets were not sold

Total number of seats = 17 x 22 = 374

Number of tickets sold = £2587.50 / £7.50 = 345

So 345 people filled 345 seats

Unoccupied seats = 374 - 345 = 29
