Did you solve this? I need it too.
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

Answer:
The answer is 55 6/9, but when simplified, it is 55 1/3
#9 is yes because 12 is double 6. 6+6=12 I don't know #10. Sorry!
-10x -120-11x
combine like terms so -10-11= -21x-120
