Answer
Explanation:
Step1: Analyze the expression
The total earnings expression is $2000 + 1000x$. Here, $2000$ is the base - salary (constant part) and $1000x$ is the commission part where $x$ is the number of cars sold.
Step2: Determine commission per car
The coefficient of $x$ in the commission part $1000x$ represents the commission per car. Since the coefficient of $x$ is $1000$, the commission per car is $1000$.
