Question

Sarah took the advertising department from her company on a round trip to meet with a potential client. Including Sarah a total of 10 people took the trip. She was able to purchase coach tickets for ​$320 and first class tickets for ​$1290. She used her total budget for airfare for the​ trip, which was ​$9020. How many first class tickets did she​ buy? How many coach tickets did she​ buy?

Answer 1

1. Start with your known values for each type of seating, coach and first class.
2. One can guess and check for this, so for instance,
$1290 * 6 = $7740
and,
$320 * 4 = $1280
Finally, $7740 + $1280 = $9020
A quick note: Sarah probably purchased more first-class tickets than coach tickets because $1920 is a lot more than $320. Meeting her budget total would most likely mean more first-class seats
