Answer:
Step-by-step explanation:
x=ticket cost in Japan
y=ticket cost in Switzerland
3x+2y=79.93
2x+3y=75.87
2/3(2x+3y=75.87) --> 4/3x+2y=50.58
3x+2y=79.93
-
4/3x+2y=50.58
----------------------------
5/3x=29.35
3/5(5/3x=29.35) --> x = 17.61
plug x back in to find y:
3(17.61)+2y=79.93 --> 52.83+2y=79.93
2y=27.1
1/2(2y=27.1) --> y=13.55
x = 17.61
y=13.55
This means:
In Japan the average cost is $17.61
In Switzerland the average cost is $13.55
