Answer:
The average cost of a movie ticket in Japan is $17.86 and the average cost of a movie ticket in Switzerland is $13.75
Step-by-step explanation:
The question seems to be incomplete. Here is a similar question and the solution:
Average movie prices in the United States are, in general, lower than in other countries. It would cost $81.08 to buy three tickets in Japan plus two tickets in Switzerland. Three tickets in Switzerland plus two tickets in Japan would cost $76.97. How much does an average movie ticket cost in each of these countries?
Step-by-step explanation:
Let the cost of tickets in Japan be $x and the cost of tickets in Switzerland be $y.
From the question,
It would cost $81.08 to buy three tickets in Japan plus two tickets in Switzerland. That is
3x + 2y = 81.08 ...... (1)
Also from the question,
Three tickets in Switzerland plus two tickets in Japan would cost $76.97. That is
2x + 3y = 76.97 ...... (2)
Multiply equation (1) by 2, so that we get
6x + 4y = 162.16 ...... (3)
and multiply equation (2) by 3, so that we get
6x + 9y = 230.91 ...... (4)
Now, Subtract equation (3) from equation (4), we get
5y = 68.75
y = 68.75/5
y = 13.75
Put the value of y into equation (1) to determine x
3x + 2y = 81.08
3x + 2(13.75) = 81.08
3x + 27.5 = 81.08
3x = 81.08 - 27.5
3x = 53.58
x = 53.58/3
x = 17.86
∴ x = 17.86 and y =13.75
Hence, the average cost of a movie ticket in Japan is $17.86 and the average cost of a movie ticket in Switzerland is $13.75.
