To determine the number of sales David needs to make, we can set up an inequality using the given information.
Let's say the number of cars David needs to sell in a month is represented by "x". We know that David earns a salary of $750 a month, plus a commission of $300 per car sold. So the total amount David earns in a month is given by:
Total earnings = Salary + Commission
Total earnings = $750 + $300x
David needs to earn a minimum of $3,500 per month. Therefore, we can set up the inequality:
Total earnings ≥ $3,500
Substituting the expression for total earnings, we get:
$750 + $300x ≥ $3,500
Using the math editor, we can write this inequality as:
750 + 300x ≥ 3500
