2. Determining opportunity cost Juanita is deciding whether to buy a skirt that she wants, as well as where to buy it. Three stores carry the same skirt, but it is more convenient for Juanita to get to some stores than others. For example, she can go to her local store, Discounted price located 15 minutes away from where she works, and pay a Marked-up price marked-up price of $122 for the skirt: Juanita's office Original price Travel Time Each Way Price of a Skirt Store (Minutes) (Dollars per skirt) Local Department Store 15 122 Across Town 30 90 Neighboring City 60 78 Juanita makes $60 an hour at work. She has to take time off work to purchase her skirt, so each hour away from work costs her $60 in lost income. Assume that returning to work takes Juanita the same amount of time as getting to a store and that it takes her 30 minutes to shop. As you answer the following questions, ignore the cost of gasoline and depreciation of her car when traveling. Complete the following table by computing the opportunity cost of Juanita's time and the total cost of shopping at each location. Opportunity Cost of Time Price of a Skirt Total Cost Store (Dollars) (Dollars per skirt) (Dollars) Local Department Store 122 Across Town 90 Neighboring City 78 Assume that Juanita takes opportunity costs and the price of the skirt into consideration when she shops. Juanita will minimize the cost of the skirt she buys it from the

70- 60- B 50- 40- 30- Suppose Naomi consumes two goods: good 1 and good 2. Last year, the price of good 1 was $2.00 and the price of good 2 was $3.20. Given these prices, Naomi maximized satisfaction consuming bundle A, as indicated in the figure to the right. However, this year, the price of good 1 has increased to $6.00 and the price of good 2 has changed to $2.40. Given these prices, Naomi would be equally well off at consumption bundle B. Calculate a Laspeyres cost-of-living index for Naomi using 100 as the base for last year. In particular, the Laspeyres index for this year is ☐. (Enter your response rounded to two decimal places.) The Laspeyres index suggests inflation has been percent over the year. (Enter your response rounded to two decimal places.) The Laspeyres cost-of-living index overstates the rate of inflation because it assumes that consumers do not alter their consumption patterns as prices change. Naomi's true cost-of-living increase has been ☐ percent. (Enter your…
