Understanding Variables in Real-World Scenarios

Mrs. Becker's lesson 31 focuses on understanding tables and equations, specifically independent and dependent variables. The lesson includes examples such as calculating reading minutes, website design, and movie streaming costs. Students are guided through exercises to reinforce their understanding of these concepts.

What is the primary characteristic of an independent variable?

• It changes based on the dependent variable.

• It affects the dependent variable.

• It remains constant throughout the experiment.

• It is always a numerical value.

In the example of Marcos' reading, what is the dependent variable?

• The number of books read

• The total number of minutes read

• The number of days read

• The number of pages read

How is the total number of websites Kirra can design calculated?

• By multiplying the number of weeks by three

• By adding the number of weeks to the number of websites

• By subtracting the number of weeks from the number of websites

• By dividing the number of weeks by three

What is the independent variable in Priya's movie streaming example?

• The total cost per month

• The cost per movie

• The number of movies watched

• The monthly fee

What equation represents the total cost of Priya's movie streaming?

• D = 1.50 + 5M

• D = 5M + 1.50

• D = 1.50M + 5

• D = M + 1.50

What is the constant in the equation for Priya's streaming costs?

• The number of movies watched

• The monthly fee

• The cost per movie

• The total cost

In the pencil purchasing example, what does the variable 'P' represent?

• The price per package

• The number of pencils per package

• The number of packages

• The total number of pencils

In the example of Charlotte's reading, what is the independent variable?

• The number of books read

• The number of weeks

• The number of pages read

• The total reading time

In the school supplies example, what does the variable 'T' represent?

• The cost of the pencil box

• The total cost of supplies

• The number of notebooks

• The cost per notebook

How is the total number of pencils calculated in the example?

• By adding the number of packages to the number of pencils

• By multiplying the number of packages by 12

• By subtracting the number of packages from the number of pencils

• By dividing the number of packages by 12
