Beto is selling raffle tickets to raise money for his school band. The tickets cost $12 each. Beto’s goal is to make at least $200. He’s already sold enough tickets to bring in $96. Write an inequality to represent this situation. How many more tickets does Beto need to sell to at least make his goal?

x ≥ 8 2/3 

Beto must sell at least 9 more tickets.
