The 10 principles are divided into three categories: Decisions Involve Tradeoffs This refers to the concept of making compromises. A person may have to give something up to get something else they want more.

What they mean by this is that, for example, you might get a free bowl of soup at the student co-op, but the soup is not free because you have to give up minutes waiting in line to be served.
The cost of something is what you give up to get it: Making a decision requires comparing the costs and benefits of alternative courses of action.
The cost of one option is not how much it will cost in dollar terms, but rather the value of your second best alternative. For more explanation, see understanding the cost benefit analysis.

Markets are usually a good way to organise economic activity: For example, if there is an oversupply of wheat on the world market then individual farmers will lower the price they charge until they can sell all of their wheat.
Lower wheat prices will also likely reduce the total quantity of wheat that farmers decide to produce. Governments can sometimes improve market outcomes: Sometimes a market may fail to allocate resources efficiently, and government regulation can be used to improve the outcome.
Market failures can occur due to the existence of public goodsmonopolies and externalities. For example, an electricity supplier might have a monopoly.
