Ok so 18x3=8x+128+10x (multiply the 8 with the stuff in the parenthesis) now you combine like terms so 54 = 128+18x now you have to get the numbers together so you subtract 128 ~> -74 = 18x then you divide -74/18 which is about -4.1 so x= -4.1
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
