Housing Price Index. Realtors use an index to compare housing prices in major cities. The housing price index values for several cities are given in the table below. Use the following formula to answer the questions. index of other town
City | Index | City | Index |
Atlanta | 100 | Las Vegas | 115 |
Boston | 146 | Los Angeles | 190 |
Chicago | 105 | Miami | 161 |
Dallas | 121 | Phoenix | 122 |
Denver | 136 | San Francisco | 172 |
