Question 1101942
Sarah took the advertising department from her company on a round trip to meet with a potential client. Including Sarah a total of 8 people took the trip. She was able to purchase coach tickets for $380 and first class tickets for $1180. She used her total budget for airfare for the​ trip, which was $5440.How many first class tickets did she​ buy? How many coach tickets did she​ buy? 
-----
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)
