The average cost of tickets in Japan and Switzerland are $17.49 and $13.42 respectively.
It would cost $79.31 to buy three tickets in Japan plus two tickets in Switzerland.
Three tickets in Switzerland plus two tickets in Japan would cost $75.24.
Therefore,
let
x = cost of Japan tickets
y = cost of Switzerland tickets
Hence,
3x + 2y = 79.31
2x + 3y = 75.24
3x + 2y = 79.31
3x + 4.5y = 112.86
2.5y = 33.55
y = 33.55 / 2.5
y = $13.42
3x + 2(13.42) = 79.31
3x = 79.31 - 26.84
3x = 52.47
x = 52.47 / 3
x = $17.49
Therefore, the average cost of tickets in Japan and Switzerland are $17.49 and $13.42 respectively.
