Independent and Dependent Variables

Master independent and dependent variables! Practice identifying them in word problems, tables, and graphs.

1. Morris Middle School is organizing a walk-a-thon fundraiser. Students are asking people to pledge (donate) £0.10 for each lap around the track they walk.Which of the following statements best describes the table? The number of laps is the dependent variable and the total money is the independent variable. The number of laps is the independent variable and the total money is the dependent variable. The number of laps and total money are both independent variables. The number of laps and total money are both dependent variables. 2. Fill in the blanks below. The total cost of the cupcakes sold is dependent on the number of cupcakes sold. Therefore, the number of cupcakes sold is the independent variable, and the total cost of the cupcakes sold is the dependentvariable. 3. Identify the independent and dependent variables on the graph. Type Independent VariableorDependent Variable in the correct places on the graph. Dependent Variable Independent Variable 4. The students at Dobie High School are collecting food for a local food bank. The amount of food collected will determine the number of trucks needed to deliver the food to the food bank. f = the amount of food collected t = the number of trucks needed to deliver the food f is the independent variable and t is the dependent variable t is the independent variable and f is the dependent variable f and t are both dependent variables f and t are both independent variables 5. Fill in the blanks below. The number of tickets sold is the independent variable. The total cost of the tickets is the dependent variable. The total cost of the tickets is dependent on the number of tickets sold.
