Suppose now that the price of flour (?1?1) varies depending on how much the baker buys. Specifically, if the baker buys fewer than 100 pounds of flour, the price per pound is ?1?1; if the baker buys between 100 and 199 pounds, the cost per pound decreases to ??1?1? (notice then that ??1<?1?1?<?1). Lastly, if the baker buys 200 or more pounds of flour at once, the cost per pound decreases further to ???1?1?. Notice then that ???1<??1<?1?1?<?1?<?1. Which of the following statements are correct?
