Bryan sells cars. He makes a salary of $500 a week, plus $150 for every car he sells. This week, he wants to make at least $2000. How many cars does he need to sell? Write an equation and solve.
Let C be the number of cars Bryan sells.
Bryan's salary is 500 + 150C
To make at least $2000, 500 + 150C ≥ 2000.
Subtracting 500 from both sides we get 150C ≥ 1500.
Dividing both sides by 150, we get C ≥ 10.
Bryan needs to sell at least 10 cars. Answer: \boxed{10}.
