Answer:
3 1st class tickets
5 coach tickets
Explanation:
Quantity:: C + F = 8
Value:: 380C + 1180F = 5440
Modify;:
1180C + 1180F = 1180*8
380C + 1180F = 5440
Subtract and solve for "C"::
800C = 4000
C = 5 (# of coach tickets)
Let x = number of 1st class tickets
8-x = number of coach tickets
and
She bought 3 1st class tickets
