Two brothers, Andile and Beki, want to join a gym for one year. Andile decides to join Gym Aerolux and Beki decides to join Gym Bodyworx. The monthly fee for Aerolux is R125 with no registration fee and the monthly fee for Bodyworx is R100 with R250 registration fee.

Answer 1

The monthly fee for Gym Aerolux is independent as Andile is not required to pay registration fee while for Gym Bodyworx the monthly fee is dependent on Beki paying the registration fee; this makes the monthly fee dependent on the registration fee.

So the monthly fee for Gym Aerolux and the registration fee for Gym Bodyworx are the input values.
