Chapter 2.4, Problem 24E
Pizza Cost and Subway Fare. The “pizza connection” refers to the observation that in New York City, the cost of a slice of pizza is always about the same as the subway fare. In Exercises 21–24, use the CPI values from Table 2.2 and the data in the following table.
24. Subway Fare in 1990. Using the CPI values from the above table and Table 2.2, determine what the subway fare should have cost in 1990 if it cost $2.75 in 2015 and prices had risen with the CPI. What does this tell you about how actual subway fares changed compared to the CPI?
