Answer:
These actions support the notion of capitalism, an example of A. non-material culture.
Step-by-step explanation:
While material culture refers to the physical pieces that make-up a culture, non-material culture refers to the ideas, values, or thoughts that make up a culture. Dress codes, hairstyles, appropriateness of language and many other accepted ideas and behaviors are included in the notion of non-material culture.
The description in the question is of Americans paying for services such as haircuts, trips to the dentist, or transportation. Even though they are not literally buying a product and taking it home - they don't own the bus or the metro after paying to use it -, they accept the idea of paying for it, to use it. That is a non-material culture example related to capitalism.
