In the example problem, how much does each person pay for their ticket?

• $20

• $5

• $15

• $10

Why is Diagram A incorrect in the example problem?

• It shows the total amount as $100.

• It shows only one person paying for the ticket.

• It shows each person paying different amounts for lunch.

• It shows each person paying $5 for the ticket.

What does Diagram B correctly represent in the example problem?

• Each person paying $10 for lunch and $5 for the ticket.

• Each person paying $5 for lunch and $10 for the ticket.

• Each person paying $5 for lunch and $5 for the ticket.

• Each person paying $10 for lunch and $10 for the ticket.

How can the equation for Diagram B be written?

• 5x = 120

• 5(x + 10) = 120

• 5x + 10 = 120

• x + 10 = 120

What is the equation for Diagram A in the example problem?

• 5x = 120

• 5(x + 10) = 120

• 5x + 10 = 120

• x + 10 = 120

In the second example, what is the equation for Diagram A?

• 3(x + 4) = 45

• 3x + 4 = 45

• x + 4 = 45

• 3x = 45

What is the equation for Diagram B in the second example?

• 3x = 45

• 3(x + 4) = 45

• 3x + 4 = 45

• x + 4 = 45

Which diagram represents the equation 4x + 5 = 101?

• Diagram A

• Diagram B

• None of the above

• Diagram C

What is the correct equation for the green diagram in the multiple choice example?

• 4(x + 5) = 101

• x + 9 = 101

• 4x + 5 = 101

• x + 4 + 5 = 101
