Kitchen Fact: Cooked food stored in the refrigerator should be eaten in 3 to 4 days. After food is cooked, it should sit out at room temperature no more than two hours before being refrigerated to slow down bacteria growth. But once stored in the fridge, leftovers should be eaten up within three to four days because bacteria can still grow even at refrigerator temperatures. To help you remember how long something has been in the fridge, we recommend labeling it with the date it was cooked to help you keep track!
Opportunity cost is always measured by how much you give up of the next best alternative to get what you want. Opportunity Costs and Production Possibilities The production possibility curve illustrates the principle of opportunity cost for an entire economy.
Economic growth is the sustained expansion of production possibilities. If more capital is accumulated production possibilities increase and the PPF shifts outward. The (opportunity) cost of economic growth is that resources used to increase capital cannot be used to produce current consumption goods and services. 2013 Pearson Education, Inc.
