(2 marks) (b) What is the opportunity cost per ipad if the economy moves production from Point c to Point d? (3 marks) (c) Without doing any calculations, would the opportunity cost in moving from Point d to Point e be higher or lower than the opportunity cost you calculated in Part (b)? Explain your answer. (3 marks) (Approximate numbers read off the chart are ok.)
