Step-by-step explanation:

Since Sarah took the advertising department from her company on a round trip to meet with a potential client and, including Sarah, a total of 17 people took the trip, if she was able to purchase coach tickets for $ 350 and first-class tickets for $ 1100, and she used her total budget for airfare for the trip, which was $ 12,030, to determine how many first-class and coach tickets did she buy, the following calculation must be performed:

10 x 350 + 7 x 1100 = 3500 + 7700 = 11200

9 x 350 + 8 x 1100 = 3150 + 8800 = 11950

So Sarah bought 9 coach tickets and 8 first class tickets.
