Cost Analysis in Group Activities

The video tutorial covers the concept of independent and dependent variables using two examples: purchasing pencils and calculating costs for a mini golf group rate. It explains how to set up equations to determine the total number of pencils based on packages and the total cost based on the number of friends. The tutorial emphasizes understanding the relationship between variables and how they affect outcomes.

What is the independent variable in the example of Sarah purchasing pencils?

• The total number of pencils

• The number of packages

• The color of the pencils

• The price of each pencil

In the equation n = 12p, what does 'p' represent?

• The number of students

• The price per package

• The number of packages

• The total number of pencils

How many pencils are there in 5 packages?

• 48

• 60

• 72

• 84

What is the fixed cost in the miniature golf example?

• $20

• $5 per person

• $15

• $3 per person

In the golf example, what does the variable 'F' stand for?

• The number of friends

• The total cost

• The number of games played

• The fixed cost

What is the formula for calculating the total cost in the golf example?

• C = 20 + 3F

• C = 3 + 20F

• C = 3F + 20

• C = 20F + 3

If you have 7 friends, what is the total cost for the golf game?

• $50

• $47

• $44

• $41

What is the dependent variable in the golf example?

• The number of friends

• The total cost

• The fixed cost

• The number of games played

How much does each additional friend add to the total cost?

• $2

• $3

• $4

• $5

Why is the number of friends considered an independent variable?

• Because it is not related to the cost

• Because it affects the total cost

• Because it changes the fixed cost

• Because it is a constant value
