Answer:
a framing bias.
Explanation:
In this scenario, Rodrigo is subject to a framing bias. This bias explains how people's decisions are affected by how situations , words or settings are framed. Even though price at both stores are the same, Pearls for Her store created a relativism factor; it showed a higher original price and a 20% discount which makes Rodrigo think that he'a getting a bargain hence making him lean more towards actually buying the necklace there and not at Murphy's Jewelry store.
