Introduction

In this discussion, we will explore the relationship between the total cost of bagels and the number of bagels purchased. Tallulah is buying bagels for a family gathering, and each bagel costs $1.25. We will analyze how the total cost changes as the number of bagels purchased increases.

Independent Variable

What is the Independent Variable?

The independent variable, denoted as $x$ , represents the number of bagels purchased. In other words, it is the variable that is being changed or manipulated in the experiment.

Why is the Number of Bagels Purchased the Independent Variable?

The number of bagels purchased is the independent variable because it is the factor that is being controlled and changed in the experiment. By varying the number of bagels purchased, we can observe how the total cost changes.

Dependent Variable

What is the Dependent Variable?

The dependent variable, denoted as $y$ , represents the total cost of the bagels purchased. In other words, it is the variable that is being measured or observed in response to the change in the independent variable.

Why is the Total Cost the Dependent Variable?

The total cost is the dependent variable because it is the outcome or result of the experiment. By changing the number of bagels purchased, we can observe how the total cost changes.

Relationship Between Total Cost and Number of Bagels Purchased

What is the Relationship Between Total Cost and Number of Bagels Purchased?

The relationship between total cost and number of bagels purchased is a linear relationship. This means that as the number of bagels purchased increases, the total cost also increases at a constant rate.

Why is the Relationship Linear?

The relationship is linear because each bagel costs a fixed amount of $1.25. Therefore, for every additional bagel purchased, the total cost increases by $1.25.

Equation of the Relationship

What is the Equation of the Relationship?

The equation of the relationship between total cost and number of bagels purchased is:

$y = 1.25x$

where $y$ is the total cost and $x$ is the number of bagels purchased.

Why is the Equation Linear?

The equation is linear because it represents a straight line with a constant slope of 1.25.

Graph of the Relationship

What is the Graph of the Relationship?

The graph of the relationship between total cost and number of bagels purchased is a straight line with a positive slope.

Why is the Graph a Straight Line?

The graph is a straight line because the relationship is linear. As the number of bagels purchased increases, the total cost also increases at a constant rate.

Conclusion

In conclusion, the relationship between total cost and number of bagels purchased is a linear relationship. The equation of the relationship is $y = 1.25x$ , and the graph of the relationship is a straight line with a positive slope. This means that as the number of bagels purchased increases, the total cost also increases at a constant rate.
