Final answer:
Amy's decision to use her savings for a beach trip instead of theater camp appears to be an instant zone decision, emphasizing short-term pleasure over long-term goals related to her passion for theater and potential college major.
Step-by-step explanation:
The question asks us to evaluate Amy's decision to spend her savings on a beach trip with friends rather than saving for theater camp, which is important for her long-term goals. Given that Amy's passion lies with theater and her intention to major in it at college, using the savings for the beach trip seems to represent a choice that prioritizes short-term gratification over long-term objectives. This is commonly known as an instant zone decision. The scenario about Selena and the concept of sunk costs implies that choices should be made based on future benefits and costs rather than past expenses. Therefore, if Amy's decision to go to the beach negatively impacts her ability to attend theater camp, it may not align with her long-term goals and might be considered an unwise use of her finances from a future-looking perspective.
