Answer:
In Japan, the average ticket costs $17.73.
In Switzerland, the average ticket costs $13.45
Explanation:
80.09-75.81=3j+2s-(2j+3s)
4.28=j-s
So a ticket from Japan costs $4.28 more than a ticket from Switzerland. so we can write the equation:
3s+2(s+4.28)=75.81
5s=67.25
s=13.45, j=13.45+4.28=17.73
