Question

1 dependent variable
a. total cost per month
2 independent variable
b. number of audiobooks downloaded
c. the additional fee
d. the cost of each audiobook

Explanation:

To determine the independent and dependent variables, we analyze the relationship: The total cost per month (dependent variable) depends on the number of audiobooks downloaded (independent variable), as the cost changes based on how many audiobooks are downloaded.

1. The dependent variable is the total cost per month (a) because it depends on the number of audiobooks downloaded.
2. The independent variable is the number of audiobooks downloaded (b) because it is the variable that we can change or that affects the dependent variable.

Answer:

1. a. total cost per month
2. b. number of audiobooks downloaded
