18.) The cost of textbooks for a school increases with the average class size. Identify the independent and dependent quantity i

son4ous [18]

The independent quantity is the average class size and the dependent quantity is the cost ⇒ c

Step-by-step explanation:

Lets revise the meaning of dependent and independent variables

The dependent variable is the one that depends on the value of some other number
The dependent variable is the output value and the independent variable is the input value
Ex: if y = 2x + 3, x is the input and y is the out put, then is independent variable and y is dependent variable

∵ The cost of the textbook increases with the average class size

- The cost of the textbooks depends on the average of the

class size

∴ The input is the average class size

∴ The output is the cost of the textbooks

∵ The input variable is independent variable

∵ The output variable is dependent variable

∴ The average of the class size is independent

∴ The cost of the textbooks is dependent

The independent quantity is the average class size and the dependent quantity is the cost
