Identifying Dependent and Independent Variables

The video tutorial explains the concepts of dependent and independent variables using practical examples. It starts with April's earnings based on her work hours, illustrating how the amount of money she earns depends on the hours worked. The tutorial then shifts to Mark's cupcake sales, showing how the number of cupcakes sold determines his total earnings. The lesson concludes by reinforcing the understanding of these variables and their roles in different scenarios.

In April's work scenario, what is the independent variable?

• The number of hours April works

• The garden center's opening hours

• The number of plants April waters

• The amount of money April earns

What determines the amount of money April earns?

• The day of the week

• The number of hours she works

• The number of customers she serves

• The type of work she does

In Mark's cupcake scenario, what is the dependent variable?

• The number of customers Mark has

• The total amount of money Mark earns

• The price of each cupcake

• The number of cupcakes Mark sells

Which variable affects the other in Mark's scenario?

• The amount of money Mark earns affects the number of cupcakes he sells

• The price of cupcakes affects the number of customers

• The number of cupcakes Mark sells affects the amount of money he earns

• The number of customers affects the price of cupcakes

What is the main lesson learned from both scenarios?

• How to calculate earnings

• How to sell more cupcakes

• The relationship between dependent and independent variables

• The importance of working long hours
