Let's analyze the given information about Alayna's parking fee:
1. She parks her car in a lot that charges by the quarter-hour.
2. The table shows the parking fee in dollars with respect to the duration in hours.
Here is the table for reference:
\begin{tabular}{|l|c|c|c|c|c|c|}
\hline Time (hours) & 0.25 & 0.5 & 0.75 & 1 & 1.25 & 1.5 \\
\hline Parking Fee & [tex]$\$[/tex] 0.50[tex]$ & $[/tex]\[tex]$ 1.00$[/tex] & [tex]$\$[/tex] 1.50[tex]$ & $[/tex]\[tex]$ 2.00$[/tex] & [tex]$\$[/tex] 2.50[tex]$ & $[/tex]\[tex]$ 3.00$[/tex] \\
\hline
\end{tabular}
To answer the question:
1. Time (hours) is the independent variable. This is because the parking fee depends on the amount of time Alayna parks her car. Since time is the independent variable, it should be placed on the horizontal axis (also referred to as the x-axis).
2. Parking fee (dollars) is the dependent variable. This is because the parking fee changes based on the time Alayna spends in the parking lot. Since the parking fee is the dependent variable, it should be placed on the vertical axis (also referred to as the y-axis).
So, the correct choices are:
- Time is the independent variable and should be placed on the horizontal axis.
- Parking fee is the dependent variable and should be placed on the vertical axis.
