Explanation:

Step1: Define independent and dependent variables

The independent variable is the one that is controlled or changed. The dependent variable depends on the independent variable.

Step2: Analyze the table

In the table, the number of months is being changed (1, 3, 5, 7, 9 months). The balance in savings depends on the number of months passed.

Answer:

The independent variable is the number of months because it can be controlled (Marcus decides how many months to save for). The dependent variable is the balance because its value depends on the number of months of saving.
