Let's analyze the given situation:
1. Time as Variable:
- Time is the variable that is being measured independently regardless of the parking fee. Therefore, it is not influenced by another factor in this context.
- Hence, time is the independent variable.
2. Parking Fee as Variable:
- The parking fee depends on the amount of time Alayna parks her car. It changes according to the time spent.
- Thus, the parking fee is the dependent variable.
3. Placement on the Axes:
- The independent variable is generally placed on the horizontal axis, known as the x-axis.
- The dependent variable is typically placed on the vertical axis, known as the y-axis.
Given these points, the correct answers are:
- Time is the independent variable and should be placed on the x-axis.
- Parking fee is the dependent variable and should be placed on the y-axis.
So, we can fill in the blanks as follows:
- Time is the __independent__ variable and should be placed on the __x-axis__.
- Parking fee is the __dependent__ variable and should be placed on the __y-axis__.
