Answer 1

To determine which facts are NOT needed to solve the problem, we first need to identify the essential information for each part of the question.

1. Roller Coaster Problem:

   • We need to find out the number of loops and tunnels the roller coaster has.
   • Relevant information: "It has 3 loops" and "a tunnel."
   • Non-relevant information: "The roller coaster is the most popular ride at the fair," "has 8 hills."

   Therefore, the unnecessary facts for this problem are:

   • The roller coaster is the most popular ride at the fair.
   • It has 8 hills.

2. Boxerville Carnival Attendance Problem:

   • We need to find out how many people attended the Boxerville carnival on the weekend (Saturday and Sunday).
   • Relevant information: "On Saturday, 800 people attended," "On Sunday, 650 people attended."
   • Non-relevant information: "On Monday, 250 people attended," "On Tuesday, 350 people attended."

   Thus, the unnecessary facts for this problem are:

   • On Monday, 250 people attended.
   • On Tuesday, 350 people attended.

In summary, the non-essential facts in both problems are:

• The roller coaster is the most popular ride at the fair.
• It has 8 hills.
• On Monday, 250 people attended.
• On Tuesday, 350 people attended.
