Match the scarce resource with the choice made and its opportunity cost:
Time and money ↔️ Choosing to work extra hours for more income ||| Opportunity Cost: The leisure time and relaxation given up
Capital and skilled labor ↔️ Investing in a new factory instead of expanding marketing ||| Opportunity Cost: Potential increase in brand visibility foregone
Tax revenue ↔️ Allocating funds to education instead of infrastructure ||| Opportunity Cost: Infrastructure projects delayed
