68 UNIT 2 Macroeconomics LESSON 2 ACTIVITY 11 (continued) Year 1 as well as in the base year. The rate of change in this index is determined by looking at the per- centage change from one year to the next. If, for example, the consumer price index were 150 in one year and 165 the next, then the year-to-year percentage change is 10 percent. You can compute the change using this formula: Price change change in CPI beginning CPI X 100 Here's the calculation for the example above: 165 150 Price change = x 100 = 10% 150 Fill in the blanks in Figure 11.2, and then use the data to answer the questions.
