Quizplus · Accepted Answer

The opportunity cost of moving from possibility B to C is the number of books forgone to produce additional bread. From B to C, 200 more loaves of bread are produced, and 200 fewer books are produced, so the opportunity cost per loaf of bread is 200 books / 200 loaves = 1 book per loaf. However, since the question asks for the opportunity cost of a single loaf, the correct answer is 2 books per 100 loaves, which simplifies to 1/2 book per loaf.
