Question

 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 $180 and first class tickets for $1020. She used her total budget for airfare for the trip, which was $3120 How many first class tickets did she buy? How many coach tickets did she buy?

Answer 1

Coach ticket = $180

 

first class ticket = $1020

 

people = 8

 

Let x be number of coach tickets

 

Then number of first class tickets = (8 - x)

 

 

x * 180 + (8 - x) * 1020 = 3120

 

 

180 X + 8 * 1020 - 1020 x = 3120

 

 

180 x + 8160 - 1020 x = 3120

 

 

180 x - 1020 x = 3120 -8160

 

 

- 840 x = - 5040

 

 

840 x = 5040

 

x = 6

 

So 6 coach class tickets and 2 first class tickets
