Amanda is a high school student. all of her friends buy their jeans from express, so she decides to buy express jeans even though levi's fit her better. amanda's purchasing decision is most influenced by factors.

Extrinsic factors.

Explanation:

Extrinsic factors in decision making are driven by an external motivation. In the case of Amanda, she is possibly motivated by social acceptance.  The other side would be intrinsic motivation, which is driven from internal interest.

A clear example to illustrate the difference would be reading books: you can do so because you need a good grade in an exam (extrinsic) or because you enjoy acquiring new knowledge (intrinsic).
