Question

You spend c dollars for p identical pairs of pants. A friend claims that because c increases if you increase p and p increases if you increase c either c or p could be the independent variable. Is your friend right or wrong? Explain.

Answer 1

Your friend is wrong.

Explanation:

Since we have that you spend c dollars for p identical pairs of pants. We can represent this using:

C = kP.

Where k is the price for one pair of pants whereby the amount of dollars you spend depends on the number of pants picked.

C is the dependent variable here, depending on P and P is independent. Therefore, you have only one independent variable which is P.
