Airline fares for a flight from Dallas to Austin are $30 for first class and $25 for tourist class. If a flight had 52 passengers who paid $1360,how many first class and tourist class passengers were there?

Call the passengers in first  = x

Then  the ones in tourist class =52  - x

 

So

 

Price for first class * number  +  Price for tourist * Number =  Total Revenue

 

30x  + 25 (52 - x)  =  1360   simplify

 

30x  +  1300 - 25x  = 1360

 

5x  =  1360  - 1300

 

5x   = 60    divide both sides by  5

 

x  =12  = first class passengers

 

52 -12   = 40  = tourist  passengers
