Rodrigo wanted to buy his wife a pearl necklace for her birthday. Murphy's Jewelry had a necklace he liked for $139, but he bought the same necklace at Pearls for Her. This pearl necklace was originally $173.75, but was on sale for 20% off, which reduced the price to $139. He was very pleased with his bargain. Rodrigo is subject to: overconfidence. overvaluing the present relative to the future. a sunk cost fallacy. a framing bias.

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.

its kinda hard to answer this when we dont have all the information that we need.
