Solution

Since there is a partially fixed component and varying component and the varying component varies with the kilometres travelled.

In the equation $x + 10 y = 200$ , $y$ is the variable varying with the kilometres travelled since it is multiplied by 10 and $x$ is the fixed component which is independent of the kilometre.

Answer is x
