Final answer:
Victor and Michael can apply the concept of opportunity cost to buy school clothes by prioritizing their purchases within a set budget, similar to the example of José forgoing a fourth T-shirt to buy movies.
Step-by-step explanation:
Based on the reference information provided, Victor and Michael could employ a similar strategy as José to buy their school clothes. In practical terms, this would involve making a decision based on their budget and the trade-off between quantity and quality or preference of items. For example, if Victor or Michael had a budget that allowed them to buy four T-shirts priced at $14 each, but they also wanted to buy movies priced at $7 each, they could decide to forego purchasing the fourth T-shirt. By not spending the $14 on the additional T-shirt, they could then use that money to buy two movies instead, assuming the cost of each movie is $7. This decision-making process reflects the concept of opportunity cost, where one must consider what they are giving up in order to gain something else.
