Answer:
Plan A is a better plan if Lee sells more than 13 cars.
Plan B is a better plan if Lee sells 13 or less cars.
Step-by-step explanation:
The question is no written correctly: "Lee was hired to sell cars. He must choose a commission plan for his Plan B Lee gets a base salary of $30,195 a year plus a $826 commission for each car he selle payment. He can choose PlanA tan B.or Pian A lee gets a bace salary of $27,345 a year plus a $1.044 commission for each car he sells..."
Both plans are linear.
We can express each plan as a linear function.
Plan A: [tex]E=1044C+27345[/tex]
Plan B: [tex]E=826C+30195[/tex]
The Plan A is better when he sells many cars (better comission), and the Plan B is better when he sells a few (better fixed income).
The breakeven point is when both plans pay the same:
[tex]E=1044C+27345=826C+30195\\\\(1044-826)C=30195-27345\\\\218C=2850\\\\C=2850/218=13.07[/tex]
Plan A is a better plan if Lee sells more than 13 cars.
Plan B is a better plan if Lee sells 13 or less cars.
