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?
+128407 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
