Final answer:
The cost of 1 hotdog is $4.00.
Step-by-step explanation:
The cost of 1 hotdog can be determined by finding the tradeoff Alphonso faces in choosing between burgers and bus tickets, based on the given information. Currently, Alphonso can afford 12 bus tickets and two burgers. To find the cost of one more burger, we need to determine how many bus tickets he would have to give up while staying within his budget. Since bus tickets cost 50 cents, Alphonso would have to give up four bus tickets to afford one more burger. Therefore, the cost of 1 hotdog is C) $4.00.
