Question

beth is buying rolls of film to take photos for her photography class. the table shows the relationship between the number of film rolls she buys, f, and the number of photos she can take, p. film rolls (f) | photos (p) 1 | 36 2 | 72 3 | 108 4 | 144 which of the variables is independent and which is dependent? f is the independent variable, and p is the dependent variable. p is the independent variable, and f is the dependent variable. complete the sentence. the dependent variable is always dropdown options: 36 more than, 36 less than, 36 times the independent variable.

Explanation:

Step1: Identify independent/dependent vars

The number of photos ($p$) depends on the number of film rolls ($f$), so $f$ is independent, $p$ is dependent.

Step2: Find variable relationship

Check the ratio: $\frac{36}{1}=36$, $\frac{72}{2}=36$, $\frac{108}{3}=36$, $\frac{144}{4}=36$. So $p=36f$.

Answer:

1. $f$ is the independent variable, and $p$ is the dependent variable.
2. The dependent variable is always 36 times the independent variable.
