If producing 10 phones requires sacrificing 20 burgers, what is the opportunity cost of each phone?

Opportunity cost is the value of what you give up when you make a choice. In this case, if producing 10 phones costs 20 burgers, we can find the opportunity cost of making one phone. To do this, we divide the total number of burgers sacrificed by the number of phones produced. So, 20 burgers divided by 10 phones equals 2 burgers per phone. This means that for every phone made, you are giving up the chance to have 2 burgers.
