Sarah took the advertising department from her company on a round trip to meet with a potential client. Including Serah a total of 5 people took the trip. She was ablets purchase coach tickets for $360 and first class tickets for $940. She used her total budget for airfare for the trip, which was 32980. How many first class tickets die she buy? How many coach tickets did she buy?
Let X be the number of coach tickets purchased.
So, the number of first-class tickets purchased is 5 - X.
The cost of coach tickets is 360X.
The cost of first class tickets is 940 * (5 - X).
The total cost of airfare is 360X + 940 * (5 - X) = 32980.
Simplifying the equation, we get 360X + 4700 - 940X = 32980.
Combining like terms, we get 580X = 32980 - 4700 = 28280.
Dividing both sides by 580, we get X = 28280 / 580 = 48.
Thus, Sarah purchased 48 coach tickets and 5 - 48 = <<5-48=-43>>-43 first-class tickets. Answer: \boxed{-43}.
