Average movie prices in the united states are, in general, lower than in other countries. it would cost $79.38 to buy three tickets in japan plus two tickets in switzerland. three tickets in switzerland plus two tickets in japan would cost $75.12 how much does an average movie ticket cost in each of these countries?

3j + 2s = 79.38
3s + 2j = 75.12.  3s + 2j - 3s = -3s + 75.12.  2j/2 = -3/2s + 75.12/2.
j = -1.5s +  37.56
 Then you can use substitution
3(-1.5s + 37.56) + 2s = 79.38
-4.5s + 112.68 + 2s = 79.38
-2.5s + 112.68 - 112.68 = 79.38 - 112.68
-2.5s = -33.30
-2.5s/-2.5 = -33.30/-2.5
s = 13.32
So s is 13.32 so you plug that back in and solve for j
3j + 26.64 = 79.38
3j + 26.64 - 26.64 = 79.38 - 26.64
3j = 52.74
3j/3 = 52.74/3
j = 17.58
So in Japan tickets average 17.58 and in Switzerland they average 13.32

38+105= 143, 39+104=143, and you will find then adding the numbers on opposite sides, moving inwards yields the answer 138 every time. because of this, you’re going to multiply 138 times the number of pairs, which is 34. therefore, 34*138= 4692(i’m sorry if it’s the wrong numbers, but it’s the right concept)
