Final answer:
To determine the cost for a bus with 50 people, multiply the ticket price by the number of passengers. With the ticket price increase from $0.50 to $1, Alphonso's opportunity cost for each ticket has increased, as he must forego more goods (burgers) to afford the same number of tickets within his fixed budget.
Step-by-step explanation:
The student has a schoolwork question related to determining the entrance cost for a bus with 50 people and understanding the effects of a change in the price of bus tickets on a budget constraint. Specifically, this involves understanding opportunity cost and how changes in prices affect consumer choices. To determine the cost for a bus with 50 people, one would multiply the price per trip by the number of people. However, the more intriguing part of the question delves into the consequence of Alphonso's town raising bus ticket prices from $0.50 to $1 per trip, while the price of burgers remains $2 and his weekly budget is fixed at $10.
When the price of bus tickets doubles, the opportunity cost of purchasing a ticket increases because Alphonso has to give up more of something else (burgers) to afford the tickets. The new budget constraint would show a reduced quantity of bus tickets that Alphonso can buy with his $10 budget. Additionally, if Alphonso is currently at point D, affording 12 bus tickets and two burgers, and wants one more burger, he would have to give up four bus tickets to remain within his budget. This tradeoff represents the true cost to Alphonso in terms of sacrificed bus tickets for the additional burger.
