Ответ:
The price of movie tickets in Japan is $ 17.76
The price of movie tickets in Switzerland is $ 13.321
Step-by-step explanation:
Given in question as :
Let The ticket amount in Japan = J
And The ticket amount in Switzerland = S
According to question
3 J + 2 S = $ 79.70 And
2 J + 3 S = $ 75.15
So , 6 J + 4 S = $ 159.4 ...... 1
6 J + 9 S = $ 225.45 ...... 2
Now, from eq 1 and 2
( 6 J + 9 S ) - ( 6 J + 4 S ) = $ 225.45 - $ 159.4
Or, 5 S = 66.05
∴ S = = $ 13.21
And The value of J is
2 J + 3 × ( 13.21 ) = $ 75.15
2 J = $ 75.15 - $ 39.63
2 J = $ 35.52
∴ J= = $ 17.76
Hence The price of movie tickets in Japan is $ 17.76
And The price of movie tickets in Switzerland is $ 13.321 Answer
