Stock The table presents the 2016 percentage change in the stock price for sixwell-known companies. (Data from : finance.yahoo.com .) Company Percentage change American Express +10.6% Coca-Cola − 1.0 % ExxonMobil +14.9% Hewlett Packard +63.1% Ford − 5.7 % Red Robin Gourmet Burgers − 8.0 % Suppose that we wish to determine the difference in percentage change between two of the companies in the table, and suppose that we are interested only in the magnitude, or absolute value, of this difference. Then we subtract the two entries and find the absolute value. For example, the difference in percentage change of stock price for American Express and Ford is | 10.6 % − ( − 5.7 % ) | = 16.3 % Find the absolute value of the difference between the two indicated changes in stock price . Disposable Income The following graph shows the real per capita amount of disposable income (in thousands of dollars) in the United States. (Data from: Federal Reserve Bank of St. Louis.) For each of the following, determine the years for which the expression is true, wherex is the per capita disposable income. | x − 37 , 000 | > 1000
