The question as text
11. A bus company provides services within a city. The basic fare depends on the travel distance between the departure station and the destination station. The cost per kilometre is € 0.20. Children under the age of 5 can travel for free. Children between the ages of 5 and 15 inclusive can travel with a child age ticket, which gives a 50 % discount off the kilometre fare. The senior discount (age 65+) offers 30 % off the kilometre fare. The sub-program costperkm(AGE) accepts an integer AGE (the age of a passenger), then calculates and returns the cost per kilometre. For example, costperkm(10) returns 0.1, costperkm(20) returns 0.2, costperkm(80) returns 0.14
