To determine the cost of a pizza, Polar considers the diameter of the pizza, the number of pizza toppings, and the amount of cheese. Which of the following is the dependent variable?

In this scenario, the cost of the pizza is the dependent variable. It is not fixed but varies based on the diameter of the pizza, the number of toppings, and the amount of cheese. The cost of the pizza is influenced by these independent variables. As the diameter, toppings, or cheese amount change, the cost changes accordingly. Therefore, the cost of the pizza is the dependent variable, as it depends on the values of the other variables. The diameter of the pizza, number of toppings, and amount of cheese are independent variables because they can be changed without the cost being fixed, showing that they affect the cost and are not dependent on it.
