Question 1 A train can accommodate at most 80 passengers, economy class (x) and first-
class (y) passengers. To avoid making a loss the train must carry at least ten

of first-class passengers should be at most three times the number of economy
class passengers.
First class tickets cost N$5000 while economy class tickets cost N$3000.
