Question 4 (Figure: Demand for Tuna Sandwiches) The graph shows Beatriz's weekly demand for tuna sandwiches. Tuna Sandwiches Price per sandwich $165 $12 $8 $4 0 Beatriz's individual demand curve Quantity of sandwiches (per week) If she orders three tuna sandwiches per week, what can we infer?

6. Determinants of demand The following graph input tool shows the demand for sedans in New York City. For simplicity, assume that all sedans are identical and sell for the same price. Initially, the calculator shows market demand under the following circumstances: average household income is $50,000 per year, the price of a gallon of regular unleaded gas is $3 per gallon, and the price of a subway ride is $1.50. Use the graph input tool to help you answer the questions that follow. (Note: You will not be graded on any adjustment made to the graph used in the tool.) PRICE (Thousands of dollars per sedan) Demand 100 200 300 400 500 600 700 800 900 QUANTITY (Sedans per month) Graph Input Tool Price of a sedan (Thousands of dollars) Quantity of sedans (Sedans per month) Average Income (Thousands of dollars) Price of gasoline (Dollars per gallon) Price of a subway ride Suppose that the price of a sedan decreased from $25,000 to $20,000.

Suppose an innovation in the baking process makes it possible to produce more croissants at a lower cost than ever before. Show the effect of this change on the market for croissants by shifting one or both of the curves on the following graph, holding all else constant. Note: Select and drag one or both of the curves to the desired position. Curves will snap into position, so if you try to move a curve and it snaps back to its original position, just drag it a little farther. PRICE (Dollars per croissant) QUANTITY (Croissants) Supply Demand Demand T Supply ?

9. In recent years, the number of car producers in China has increased rapidly. In fact, China now has more car brands than the United States. In addition, car sales have climbed every year and automakers have increased their output at even faster rates, causing fierce competition and a decline in prices. At the same time, Chinese consumers' incomes have risen. Assume that cars are a normal good. Draw a diagram of the supply and demand curves for cars in China to explain what has happened in the Chinese car market.
