Final answer:
This scenario illustrates budget constraints and opportunity cost in microeconomics, where Alphonso must choose how to allocate his fixed budget between burgers and bus tickets, leading to different purchasing combinations represented by Points A and F on a budget line.
Step-by-step explanation:
The scenario presented involves understanding the concept of budget constraints and opportunity cost in microeconomics. When Alphonso has a fixed budget and the prices for burgers and bus tickets are provided, he faces a choice between allocating his resources to either type of purchase. The vertical and horizontal axes represent the number of burgers he can purchase versus the number of bus tickets, respectively. Based on the given information, we can create a budget line which illustrates all possible combinations of burgers and bus tickets Alphonso can afford with his $10 weekly budget.
Point A on the budget line represents the choice of spending all his money on 5 burgers (at $2 each) and zero bus tickets. On the other hand, Point F represents the alternative of purchasing 20 bus tickets (at $0.50 each) and no burgers. This decision-making process is a fundamental concept in microeconomics where individuals have to make choices on how to allocate limited resources effectively.
