A. Y=$429x + $1,554.
Step-by-step explanation:
The reason being is that 429 dollars Is the money added each time he sells a car so X represents the amount of cars he sells which is unknown thus why it is X so it would be the amount of cars he sells (X) multiplied by 429 dollars. Adding 1,554 to the total because that is base salary so he makes that whether he sells a vehicle or does not. So itโs the amount of cars multiplied by the commission and adding on the base salary. Hope this helped.
