Assume that China and France each have 1,000 production units. With one production, China can produce either 10 containers of toys or 7 cases of wine. France can produce either 2 containers of toys or 7 cases of wine. Calculate the opportunity costs. In China, opportunity cost of producing 1 case of wine is container of toys. (Round to two decimals) In China, opportunity cost of producing 1 container of toys is cases of wine. (Round to two decimals) In France, opportunity cost of producing 1 case of wine is container of toys. (Round to two decimals) In France, opportunity cost of producing 1 container of toys is cases of wine. (Round to two decimals)
