You have 8 hours to spend at the market. But 2 of those hours will be spent volunteering at your friend's booth. The rest of the time you can ride on the rides. Each ride takes about half an hour. Write an inequality to represent your time available to spend at the fair. What is the maximum number of rides you can ride that day? What is the greatest number of rides you could ride if you need to leave 6 hours after your arrival?
