In the drama club example, what are the two items being sold?

• Costumes and props

• Tickets at the door and tickets in advance

• Popcorn and drinks

• Programs and souvenirs

What variable represents the number of tickets sold at the door?

• Z

• Y

• X

• W

What is the maximum number of tickets that can be sold for the drama club's show?

• 100

• 150

• 250

• 200

What inequality represents the goal of selling at least $1,000 worth of tickets?

• 10X + 5Y < 1000

• 10X + 5Y ≥ 1000

• 10X + 5Y = 1000

• 10X + 5Y ≤ 1000

In the second example, what does 'B' represent?

• Number of bracelets sold

• Number of books sold

• Number of bags sold

• Number of bottles sold

What is the inequality for selling more than 10 bracelets and earrings combined?

• B + R ≤ 10

• B + R > 10

• B + R < 10

• B + R ≥ 10

What inequality represents the goal of making at least $60 from selling bracelets and earrings?

• 2B + 3R < 60

• 2B + 3R = 60

• 2B + 3R ≤ 60

• 2B + 3R ≥ 60
