The number of passengers with $126 tickets is x, and
The number of passengers with $286 tickets is y
Given:
x(126)+y(286)=19204 (1) and
x+y=94 (2)
From (2) you get:
x=94-y and plug this in (1), you get:
(94-y)(126)+286y=19204
11844-126y+286y=19204
160y=7360
y=46 number of passengers with $286 tickets
x=94-46=48 number of passengers with $126 tickets
