Quizplus · Accepted Answer

Chris gives up removing 25 bags of trash to plant 73 bulbs, so the opportunity cost of planting 1 bulb is removing 1/3 (= 25/75)of a bag of trash. More generally, the opportunity cost of producing an additional unit of the good on the vertical axis is the reciprocal of the absolute value of the slope of the PPC (that is, 1/|slope|).
