You are a manager for a tech company that makes modules for drones. You use memory chips in your modules and have been buying them to store in inventory. To make the math easy, suppose you bought 1 chip two months ago and paid the then market price of $450 for the chip, bought another 1 chip one month ago and paid the then market price of $500 for the chip, and then purchased an additional 1 chip today and paid the market price of $550 for the chip. Of course, you can either sell the chips or use them in your module. What is the opportunity cost of using one of these chips today to make a module? Explain your answer.
