Suppose that Verania and Josimar are roommates that need to complete some household chores. Vacuuming and washing dishes need to be done. They know from the last time they did these chores that it takes Verania 2 hours to vacuum and 1 hour to wash dishes. It takes Josimar 3 hours to vacuum and 2 hours to wash dishes. Josimar says it does not matter which task each of them performs because Verania is faster at both tasks. Josimar’s reasoning a. is wrong. Because Verania has a comparative advantage in washing dishes, she should wash dishes, and Josimar should vacuum. b. is correct. Because Verania is faster at both tasks, there is no benefit in each volunteer specializing in one task or the other. c. is wrong. Because Verania has an absolute advantage in both tasks, she should perform both tasks herself. d. is wrong. Because Josimar has a comparative advantage in washing dishes, he should wash dishes, and Verania should vacuum.

Consider the following scenario to understand the relationship between marginal and average values. Suppose Sam is a professional basketball player, and his game log for free throws can be summarized in the following table. Fill in the columns with Sam's free-throw percentage for each game and his overall free-throw average after each game. Game Result Total Game Free-Throw Percentage Average Free-Throw Percentage Game 1 8/10 80 12/20 14/28 16/32 22/40 2 3 4 5 8/10 4/10 2/8 2/4 6/8 80 On the following graph, use the orange points (square symbol) to plot Sam's free-throw percentage for each game individually, and use the green points (triangle symbol) to plot his overall average free-throw percentage after each game. Note: Plot your points in the order in which you would like them connected. Line segments will connect the points automatically.

A company that produces brass hardware for doors has the ability to produce up to 6,500 hinges per week but then is unable to produce doorknobs. Or it can produce up to 650 doorknobs per week but then is unable to produce any hinges. In the graph below, use the straight-line tool to draw the company's production possibilities frontier, where the quantities are per week (do not use the point tool to plot endpoints). Then use the point tool to plot a point to indicate the company's maximum output where it is producing exactly three times as many hinges as doorknobs.
