What is opportunity cost?
Opportunity cost is the value of the next-best thing you give up when making a choice. If a family chose to move to California, their opportunity cost was the safe, familiar life they left behind on their farm.
How do families make trade-offs?
Families make trade-offs by evaluating what they gain and give up with each choice. If a family moved west for new land, they gained new opportunities but gave up their old home and friends—the opportunity cost of their decision.
