Look at Exercise 19.2. Compute the opportunity costs of producing sweaters and wine in both France and Tunisia. Who has the lowest opportunity cost of producing sweaters and who has the lowest opportunity cost of producing wine? Explain what it means to have a lower opportunity cost.

Answer Illustration : Opportunity Cost of producing Wine is lesser in France, Opportunity Cost of producing Sweaters is lesser in Tunisia. So, France has comparative advantage in Wine, Tunisia in Sweater.

Explanation:

Opportunity Cost is the cost of next best alternative foregone while choosing an alternative.

Opportunity Cost of producing Sweaters & Wine in France & Tunisia are quantities of other goods (Sweaters or Tunias) sacrifised while choosing either. Sweater Opportunity Cost - Wines sacrifised, Wine Opportunity Cost - Sweaters sacrifised.

The country has a comparative advantage in a good if it can produce it with relatively less opportunity cost (in terms of other good sacrifised) than other country.

Ex : Production Possibilities

                   Wine            Sweater    Trade off (Wine :Sweater)

France          10                   5              1:0.5  or 2:1

Tunisia          8                   24              1:3  or 0.33:1

prokaryotic cells do not contain a nucleus or any other membrane-bound organelle. eukaryotic cells contain membrane-bound organelles, including a nucleus. so i belive the answer is a : p hope it

since the options are not listed, when you are working on your budget you should also add water, tv, internet, miscellaneous and your 'fun' money for in your budget. when budgeting, you need to allow for fun money, and mis/accidental money so that you stick to the budget and not go crazy because you feel strapped to the budget.
