Explanation:

• For part A:
• In the equation \(8x + 20=76\), since there are 8 friends and \(x\) likely represents the cost per ticket.
• The term \(8x\) is the product of the number of friends and the cost per ticket.
• For part B:
• In the term \(8x\), the coefficient is 8.
• Given that there are 8 friends in the group, the coefficient 8 represents the number of friends.

Answer:

• A. The total cost of tickets for the 8 friends.
• B. The number of friends in the group.
