Answer:
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
