There are 14 rows of seats in a cinema. There are 15 seats in each row.
A film was shown in the cinema on Saturday,
Each ticket for the film cost £6.50
The tickets that were sold cost a total of £1274
How many tickets were not sold?

24 tickets were not sold

Step-by-step explanation:

Here, we want to get the number of unsold tickets

In each row, there are 15 seats

In the Cinema, there are 14 rows

The total number of seats is thus;

15 * 14 = 220 seats

If all the 220 seats were booked, the total amount of ticket sales would have been;

220 * 6.5 = £1430

But in this case, the amount generated is £1,274

Hence, the difference in these amounts will be;

1430 - 1274 = £156

To get the number of tickets unsold, we have to divide the amount here by the price per unit ticket

Mathematically, we have this as;

£156/£6.5 = 24

expression #3 is not equivalent. the others are.
