Question

a car salesman makes $1000 each day that he works and makes approximately $250 commission for each car he sells. if a car salesman wants to make at least $3500 in one day, how many cars does he need to sell?

Answer 1

Where do I go to get this job???

 

250c + 1000 = pay

250c + 1000 ≥ 3500

250c ≥ 2500

c ≥ 2500/250

c ≥ 10

 

He must sell at least 10 cars to make $3500 for the day.
