Betsy and her family sell hot dogs outside the stadium during local football matches. Local football matches take place every day because they are the main form of entertainment in the town. Betsy knows that demand for hot dogs will depend on whom the local team is playing against. Betsy has a large amount of hot dogs stored at home, and whatever does not get sold one day, will be stored for the next day. Based on the expected demand, Betsy determines how many hot dog carts will be needed for that day and rents the appropriate number of hot dog carts from a local supplier (the only local supplier of hot dog carts in town). The local supplier of hot dog carts is an avid football fan and therefore opens the store only for a few hours early in the morning before the game. Once Betsy has rented the hot dog carts, the store closes until the next day. Which of the following statements are correct about Betsy's business?
Choose one or more:
A. Specifically for this problem, the long run could be described as roughly 24 hours.
B. Once Betsy has rented the hot dog carts and the supplier has closed the store, Betsy is facing a long-run decision.
C. Before deciding how many hot dog carts to rent, as long as the supply store is still open, Betsy is facing a long- run decision.
D. The long run is never less than 1 year.
E. For Betsy's business, the number of hot dogs is always a variable factor and the number of hot dog carts is always a fixed factor.
