A very simple primary school question?

  1. Jan 14, 2008 #1
    MM is a restaurant making hamburgers. Suppose it sells 40 regular hamburgers per day and each hamburger needs 1 regular bun.
    Suppose buns are delivered every second day. MM is ready to order. His on-hand balance of regular buns is 25. How many buns should be ordered?

    My classmates treat this as a simple primary school question. What do you guys think?

    Oh, behave!

    In today's world we work on "just on time" delivery. Since buns are delivered "every second day", you need enough buns for two days. If you sell 40 hamburgers a day, you will need 80 buns for two days. You already have 25 buns. How many more do you need?

    Yes. But since buns are delivered "every second day", that means I will be running out of buns for tomorrow already (I just have 25 buns only). So...

    I had assumed the first delivery would be later today or early tomorrow. If you cannot get enough buns for tomorrow, there is NO way of answering this!
