A student living on a tight budget should prioritize which of the following questions before a purchase?

Prioritizing whether a purchase is necessary is crucial for someone living on a tight budget. This question encourages careful consideration of spending habits and financial needs. By evaluating the necessity of a purchase, the student can distinguish between wants and needs. This approach promotes responsible financial decision-making, which is essential for maintaining a sustainable budget and avoiding unnecessary debt.

In contrast, questioning if a cheaper version is available can be helpful but does not address the core issue of whether the purchase is essential. While concerns about friends' opinions can influence buying choices, they can lead to impulsive and unnecessary spending. Additionally, while understanding the impact on credit scores is important for long-term financial health, it may not be directly relevant to day-to-day budgeting decisions. Overall, focusing on the necessity of the purchase is the most prudent step for managing finances effectively.
