Answer:
ticket in Japan: 17.23 $
ticket in Switzerland: 13.26 $
Step-by-step explanation:
let the price of one movie ticket in Switzerland be Y
let the price of one movie ticket in Japan be X
then accordingly,
it is given that
3x + 2y = 78.21
and
2x +3y = 74.24
multiplying the first equation by 2 and second by 3 we get
6x + 4y = 156.42
6x + 9y = 222.72
subtracting 1st equation from second we get
5y = 66.3
y = 13.26
by putting in the value of y in equation 2 we get:
2x + 39.78 = 74.24
2x= 34.46
x= 17.23
