The earning of the salesperson is an illustration of a linear function.
The possible functions in the two scenarios are:
and 
The function is given as:

When the base salary is increased, a possible function is:

This is so, because 2500 is greater than 2000
When the commission rate is decreased, a possible function is:

This is so, because 0.05 is less than 0.1
So, the possible functions in the two scenarios are:
and 
See attachment for the graphs of both functions

The rule that describes the composition of transformations that maps ΔJKL to ΔJ"K"L" is Rotation 0° to 90° and reflection about the x-axis.
<h3>What is the transformations rule that was used here?</h3>
A transformation is a rule that is used to manipulate the position of a point of geometric figure.
Analyzing the figure, rotation of ΔJKL through the angle 90 degrees in a counter-clockwise direction gives us ΔJ'K'L' .
ΔJ"K"L" is been gotten also using ΔJ'K'L' through the refraction of ΔJ'K'L' across the x-axis.
In this case, rule that describes the composition of transformations that maps ΔJKL to ΔJ"K"L" is Rotation 0° to 90° and reflection about the x-axis.
