Answer: 15 vehicles
Explanation:
The first part of the question reads:
A salesperson at a car dealership earns a monthly salary of $2,400 and $250 for each vehicle sold.
The Sales person wants to get to $6,000 for the month.
Their salary already gives them $2,400 so the amount they have to make in commission is:
= 6,000 - 2,400
= $3,600
They earn $250 per car sold so the number of cars they need to sell is:
= 3,600 / 250
= 14.4
Round this up to 15 cars because rounding down to 14 would not be enough to reach the total of $6,000.
15 cars * $250 commission = $3,750 which is more than the $3,600 required so the condition has been satisfied.
To earn at least $6,000, they will have to sell 15 cars.
