  1. Assume that you have decided to make pasta for your family dinner tomorrow night. You have decided to do your grocery shopping online. Find the Online Grocer Web site. Select the Grocery aisle in the left frame of the Web site.
    1. Scroll through the list of grocery items and click on Pasta. Give the cost per gram of the Catelli Macaroni (500g) to the nearest tenth of a cent.
    2. Give the unit cost of the Unico Linguine (900g) to the nearest tenth of a cent.
    3. Assuming that your family does not care which type of pasta they have for dinner, which pasta is the better buy?
    4. Go back to the grocery aisle. Scroll through the list of grocery items, and click on Pasta Sauce. Give the unit cost of the Classico Spicy Red Pepper Spaghetti Sauce (700ml) to the nearest tenth of a cent.
    5. Give the unit cost of the Hunt's Thick & Rich Original Spaghetti Sauce (680ml) to the nearest tenth of a cent.

  2. The government calculates a number called the consumer price index (CPI) to measure the cost of living. When the CPI doubles, it means that, on average, prices have doubled. Find the Consumer Price Index. The CPI scale used in this table considers the average prices in the years 1982–1984 to be 100. Scroll to the right to find the column labeled AVG. Use the average CPI values listed in this column to answer the questions below.
    1. If an item cost $1 in 1920, about how much would you expect it to cost in 2000 if it increased in price along with the CPI?
    2. If a home was purchased for $135,000 in 1990, and the value of the home has gone up with the CPI, what is the value of the home in 2001?
    3. In 2001, a 2001 Ford Mustang two-door coupe costs about $17,000. What would you expect a new car of the same type to have cost in 1995? In 1991? Round to the nearest hundred.
